a senior vice-president in a large
Even as industrial output is hitting
new lows every passing month, India
Inc is belatedly waking up to a major
environment clearance deterrent that
is jeopardizing investments across
manufacturing, services and even
the agriculture sector.
In early 2013, the Environment
Ministry had made it mandatory to
obtain a prior environment clearance
for all investment projects involving
a construction of over 20,000 sq
mt or five acres of land. This has
already scuttled and delayed a few
projects of auto and power sector
majors, who have been told to get
environmental nods for building
or expanding industrial facilities
like factories and warehouses — a
process that takes at least 18 months
in a best-case scenario.
“Though the rules issued in
2006 explicitly kept sectors like
automobiles and manufacturing out
a delay of around two years to obtain
the green clearance.
“This makes investment planning
highly risky as there would be a
two-year lag in responding to
market forces,” said an official in
an industry chamber that is in the
process of flagging the issue with
the government.
“Moreover, the ministry considers
the cumulative construction in a
plant for this purpose. If a 19,000 sq
mt auto component plant needs to
expand by a mere 1,000 more sq mt,
it will have to seek an environment
nod for the entire plant,” pointed
out the industry executive quoted
earlier. “Given that most investments
of a viable scale involve at least five
acres of land, can the environment
clearance machinery in states and
the Centre cope with the workload
this would entail?” he inquired.

India became net steel exporter in
2013-14 after a gap of six years and
is likely to maintain the momentum
in 2014-15 as producers are looking
to dock more overseas shipment
to tide over subdued domestic

Total steel exports by India during
the last fiscal stood at 5.59 million
tons (mt), as against imports of 5.44
mt, said the Joint Plant Committee
(JPC), a unit of the Steel Ministry.
India, now the world’s fourth
largest steel maker, had been a net
steel importer since 2007-08 and the
trend continued till 2012-13 with 7.9
mt of imports and 5.2 mt of exports.
Before 2007-08, India’s exports were
more than its imports.

One of the leading research firms,
Research & Markets, has announced
the addition of the ‘Global Coating
Additives Market Report 2013-2018
- Analysis of the $8 Billion Industry’
report to their offering.
The global market, in terms of
revenue, was estimated to be worth
$6 billion in 2012, and is expected to
reach $8.7 billion by 2018, growing at
a CAGR of 6.4 per cent from 2013.
Asia-Pacific and North America
dominated the global coating
additives market demand in 2012.
Asia-Pacific is expected to remain
the largest market in the near future,
owing to increasing demand from
key countries such as China and
India.
This study estimates and projects
the global market trend of coating
plants of 1.5 mtpa capacity each in
Rajsthan, Madhya Pradesh and
Uttar Pradesh. It is also adding
clinker capacity in West Bengal and
Rajasthan by 0.8 mtpa each.
Ambuja Cement is investing
Rs 3,500 crore for setting up the
three new plants. The expansion at
Sankrail project is underway and is
slated to cost Rs 325 crore. “So far,
equipment orders have been placed
and civil work is in progress. This
project would add 0.80 mtpa grinding
capacity to the unit along with other
facilities,” said the company.
A new expansion project to set
helped India become net exporter
of steel.
While higher exports were driven
by volatility of rupee and mismatched
demand-supply situation in the
country; imports were lower mainly
due to slowdown in the domestic
economy, said JPC.
India’s steel consumption grew
by just 0.6 per cent in 2013-14, the
lowest in four years, to 73.93 mt,
impacted by a slower expansion of
the domestic economy and lower
imports.
“The low growth rate in domestic
steel consumption indicated that
base level demand conditions
continued to be weak during 2013-
14,” said JPC. .
The construction sector accounts
for around 60 per cent of the
additives until the end of 2018. Asia-
Pacific is the most dominant market
for these additives, owing to large
and growing demand from China and
growing construction industry.
Coatings are also available in
powder form which is best suited for
application where the substrate is
able to withstand curing temperature
which is more than 125C. Acrylic
and urethane-based additives are
the fastest growing product types in
these applications.
Growing construction activity,
automotive, industrial developments,
and furniture are expected to help
this market. Asia-Pacific is expected
to be the largest market for these
additives where growth is driven by
key countries such as China, Japan
and India.

of 2014, said Ambuja Cement.
However, the company said that
the cement industry is looking for an
up-cycle backed by an increase in
rural consumption and recovery in
infrastructure activity after a muted
growth for the last three years.

by a slowdown in the economy which
according to the Central Statistics
Office estimates grew by 4.9 per cent
in 2013-14, against the growth rate of
4.5 per cent in 2012-13. Sensing poor
demand in store, almost all domestic
steel producers, both public and
private, tried to export vigorously and
showed good growth in overseas
shipments last fiscal.
The Steel Authority of India (Sail)
had clocked a 30 per cent growth in
exports in 2013-14 and aims to more
than double the shipments to 1 mt in
2014-15. The Rashtriya Ispat Nigam

issue.
Hyundai Motors had proposed an
expansion of its plant in Kanchipuram
that was to take its built-up area to
around 38,000 sq mt. The company
was asked to seek an environment
clearance first as per the norms for
building construction and township
and area development activities. The
diktat to Hyundai set a precedent,
which almost all state environment
departments have used since then
to force companies to seek a green
clearance for new capex that would
take their unit’s size beyond the
20,000 sq mt thresholds.

to raise manufacturing’s share in
the economy to create millions of
jobs, but the Environment Ministry’s

Bhavan, Chandigarh
Enhanced roof durability
with MTC
Roof refurbishment is about more
than just ‘fixing’ the leaks. Have you
ever considered what will happen if
your roof failed? What is the potential
cost to the inhabitants of that building
or workplace? And what does it mean
for the person managing that facility
and their annual budget?
From a long-term perspective,
investing in a proven refurbishment
solution for your roof is a viable option
especially for owners and managers
concerned with multiple buildings,
as patching up your roof year after
year is a costly measure, both in
terms of financial requirement, and
the operational time and resource
needed to continually deal with these
on-going issues. Sika is dedicated to
sustainable development, assuming
responsibility to provide sustainable
solutions for material, water and
energy efficiency. The company
strengthens sustainability through
programmes for efficiency and safety
to achieve economic, social and
environmental progress.
Roofing failure
It is crucial that the contents within
a building are protected, especially for
those buildings containing high value
assets or operational systems. All
roofing systems will, at some stage,
reach the end of their functional life.
However the cause of a roofing failure
may not solely be down to the roof
waterproofing failing. Mechanical
damage, poor design and poor
installation are all factors that can
affect the integrity and performance
of the roof waterproofing. Each of
these factors, and more, need to be
assessed when an existing roofing
system is deemed to have failed.
The implications of the failure
need to be investigated, and
appropriate remedial or replacement
solutions specified. When selecting
the replacement roofing system,
compliance with the building
regulations needs to be achieved,
particularly those contained with
approved documents and the
refurbishment solution needs to be
durable, have minimal environmental
impact and be installed by fitters
trained in the product’s installation.
Sika MTC Technology
SikaRoof MTC (Moisture Triggered
Chemistry) Systems incorporate
a unique technology that allows
the material to use atmospheric
moisture to trigger the curing
process. This means the waterproof
membranes are capable of curing in
a wide range of conditions including
extreme temperature ranges and
humidity variations. Unlike traditional
polyurethane systems they do not
release CO2, which often causes
gassing, and application is not
delayed by adverse weather
conditions. It is not recommended
to install the SikaRoof MTC systems
when rain is imminent, as rainfall
could affect the appearance of the
product. However, once applied
the membranes are waterproof and
will not show an adverse reaction
to water. Within the SikaRoof MTC
Systems is a Sikalastic membrane
that cures to provide completely
seamless waterproof protection. Its
liquid application means it can be
easily applied to all complex detail
areas.
Zero Flame - Zero Heat Cold
applied and with no need to use a
torch, hot air guns, hot gas guns or
heating equipment such as bitumen
boilers, Sikalastic presents no fire risk
during application or once in place,
and gives contractors an opportunity
to lower insurance premiums. Once
installed the system achieves fire
ratings.

re-roofing at Gandhi Bhawan
The Gandhi Bhawan is one of
the heritage buildings under Punjab
University situated in Chandigarh,
India.
Gandhi Bhawan was built in the
early 1950s and designed by world-
famous architect Pierre Jeanneret
with a critical geometrical shape
in the roof. In due course of time
a problem of water leakage was
experienced and as a remedial
measure an additional reinforced
concrete slab was laid over the
roof with a cavity of approx 300
mm. A bituminous membrane was
installed over the concrete slab as a
waterproofing solution. However, due
to exposure conditions and stresses,
the bituminous membrane could
not provide a watertight roof and
allowed water penetration into the
gap between the two concrete layers
with stagnation and accumulation of
rain water. The challenge was to make
this roof watertight and on the other
hand maintaining the heritage look
of the structure. The owner required
a watertight roofing solution without
any disturbance to the present
surface as well as maintaining the
heritage look of the building.
Sika solution
Sika proposed Sikalastic - 618
(MTC) an advanced roofing solution
based on polyurethane liquid applied
membrane system which can be
directly applied over the existing
bituminous surface after a minimal
cleaning and removal of weak, de-
bonded bituminous membrane. The
liquid applied material was easy
to handle on such a geometrically
challenging shape of the roof and
also provided with a reflective white
surface which not only enhanced
the overall aesthetics (compared to
earlier black bituminous surface),
but also improved energy efficiency
of the building due to its higher solar
reflectance.

‘Durable construction impossible without
right usage of construction chemicals’
Your observation on the size of
domestic construction chemicals
market.
According to recent studies,
the market size of the construction
chemicals industry in India is roughly
pegged at Rs 3,500 crore, with a
potential to reach Rs 5,000 crore
over the next few years if we, as
the industry, promote ourselves
professionally and increase the level
of awareness within the construction
industry.
The construction industry should
be convinced that the usage of
construction chemicals is a benefit
and not an undue cost.
For the past five years the growth
rate for the industry is roughly 17
per cent CAGR based on available
figures. The projected growth rate
for this sector could be CAGR of
over 20 per cent, in the near future.
The growth was affected due to the
recessionary slump, but now the trend
is positive.
India’s construction chemicals
market is a combination of the
organized and unorganized sector,
with the organized sector representing
more than half of the market.
Major segments of construction
chemical (CC) industry and total sales
Segments of CC industry % of Total Sales
Admixtures 40-45%
Flooring 10-15%
Waterproofing ≈ 14%
Repair ≈ 12%
Tiling, Sealants and Others 19-20%
How do you see the demand
situation at present?
Currently, a significant chunk
of about more than 65-70 per cent
of construction chemicals is being
used for new structures. Also, old
structures, when due for repairs,
need to use construction chemicals.
The chemicals will be consumed for
enhancing life expectancy of civil
engineering assets as they cannot be
demolished. In addition, construction
chemicals engulf a large range of
products for every industry in India.
On growth drivers for construction
chemicals in India.
With growing infrastructure spend,
construction chemicals are going to
be used in concrete, and this would
mean a vast opportunity in roads,
irrigation projects, power sector,
railways, etc.
Areas like waterproofing, flooring,
industrial construction, too, are
witnessing a positive upswing due
to a rise in number of residential and
commercial projects.
“Sustainable construction should aim at
reducing the environmental impact of a building
over its entire lifecycle, including construction,
occupation, maintenance and demolition. In
a fast developing nation like India, costs are
essential and sustainable construction can
help economize cost of the structure over its life
cycle,” says Samir Surlaker, President of
apex industry body, the Construction Chemicals
Manufacturers Association (CCMA) and
Managing Director of MC-Bauchemie (India)
Pvt Ltd, in an interview with Paresh Parmar
As manufacturing grows further, the
demand for construction chemicals in
industrial usage will rise in tandem.
As rehabilitation and construction
growth accelerates, the demand for
construction chemicals will go up,
augmenting sales and turnovers.
At present, rise in awareness
on correct usage of construction
chemicals among existing users
and increasing awareness about the
industry for new users, especially in
developing areas of our nation, would
be the biggest growth drivers for the
industry.
How do you see the role of value-
addition in products towards
achieving overall performance
enhancement?
The latest technological trends
globally are slowly but surely catching
a foothold here in India. Be it PCE
admixtures for concrete, time-saving
tile adhesives, beautiful resin-based
floorings, more robust and effective
waterproofing systems, or technical
mortars like grouts, repair mortars,
and protective coatings; these
materials are currently accepted and
used across various top-tier projects
in India.
This effect has to filter down
towards normal/day-to-day usage,
something we believe, will happen
as the awareness about our industry
and correct usage of construction
chemicals grow.
Tell us about the CCMA’s role in
promoting the industry growth.
The key objective for the
association will be to promote growth
of the construction chemicals industry,
by raising awareness and quality
standards.
The response from construction
chemical manufactures is positive
with leading companies joining in to
form a strong apex body. Many raw
material suppliers to the industry, local
as well as transnational companies,
have already joined or are actively
considering joining the association in
the capacity of associate members.
With this development, the CCMA
is slowly but surely becoming the
voice of the construction chemical
industry.
Furthering the cause for technical
development, a handbook is planned
on the correct usage of construction
chemicals in collaboration with the
Indian Concrete Institute. Attempts
are already on the way to introduce
technical topics in the academic
syllabi.
Training programmes are in
advance stages of design. These
roving seminars will be taken to rural
areas as well as engineering colleges.
Another initiative is to open up local
chapters all over India.
In a very short amount of time BIS
has agreed that the CCMA will be on
key IS Code committees to take a
viewpoint of expert CCMA members
in the formulation of codes.
With this holistic approach, we are
confident of improving the systematic
use of construction chemicals. Three
years down we are firmly on track in
our objectives to increase awareness.
With two successful international C3
(Construction Chemicals Conference)
events in Mumbai and Delhi behind
us, we are also taking the initiative
further to India’s regional centres with
our C3R (Construction Chemicals
Conference Regional) events at Rajkot
and Nagpur. This initiative continues
with the successfully concluded C3
event in Chennai recently, and further
regional events in Rajasthan, and
eastern India.
Participants for these events were
end-users, specifiers, government
decision makers, etc. These seminars
also focus on problems faced by
decision makers to specify and use
these products with confidence.
International speakers were invited
who could instill confidence in our
local civil engineering fraternity about
benefits of usage of construction
chemicals. The success of our
seminar series is a good indication
that the interest in correct usage
of construction chemicals is fast
gaining ground due to the benefits in
speed, durability and lifecycle costs

sustainability. Through the medium
of CCMA, we would push forward for
better code of conduct and quality
standards relating to green products
eventually.
On the challenges confronting
the industry at present and the
opportunities ahead.
Wheels are already in motion
to interest our government in
accepting construction chemicals as
a recognized industry segment that
would support us with incentives and
rationalization of government taxes,
duties and levies.
Tax breaks in Vat, etc for the
construction chemicals industry
would be a big boost for us, since
most construction in India is still a
cost-sensitive market for construction
chemicals. Getting materials to end-
users at lower cost with fewer burdens
on manufacturers will boost the
growth of the industry as a whole. It
would also help to boost performance
and quality in construction.
In this regard, we plan to
communicate views of construction
chemicals manufacturers and
end- users to Central and state
governments by taking help of Ficci,
CII, etc.
Of course, as the awareness
grows, the market will get bigger and
focus will be on increasing technical
awareness, and awareness on usage
of construction chemicals. With this
we look forward positively to the year
ahead.
You comment on successful
completion of the 3rd edition of C3.
The Construction Chemicals
Manufacturers Association (CCMA)
hosted the third edition of ‘International
Construction Chemicals Conference
in 2014.’
The focus of the seminar was to
enrich and improve dialogue between
the construction industry and the CC
industry. The C3 event in Chennai was
a customer-centric event where our
partners in the construction industry
benefitted from people who know
construction chemicals the best -- our
construction chemical industry.
It was actively supported by
ICI, SEWC, BAI, ACCE, etc, which
generated tremendous interest in
the conference. The emphasis of
the international conference was
on improvement at the time of
construction, repairs, strengthening
and rehabilitation and protection from
future deterioration.
Delegates to C3 gained from
an insightful programme and had
the networking opportunity which is
bound to unite the industry together.

How do you see sustainability in
the current situation and what are
CCMA’s initiatives?
Sustainable construction should
aim at reducing the environmental
impact of a building over its entire
lifecycle, including construction,
occupation, maintenance and
demolition. In a fast developing
nation like India, costs are essential
and sustainable construction can help
economize cost of the structure over
its lifecycle.
While some building practices
are guided by short-term economic
c o n s i d e r a t i o n s , s u s t a i n a b l e
construction is based on best
practices that emphasize long-term
affordability, quality and efficiency.
Sustainable construction should
aim at environmental friendly
construction, and this includes
reducing repairs, rehabilitation,
rebuilding and decommissioning a
structure. Most of these issues can
be addressed by good quality durable
construction.
Construction of durable structures
is absolutely not possible without right
usage of construction chemicals. This
durability would define and enhance

11 m homes vacant
Amid housing shortage of up
to 25 million units in the country,
Urban Development Secretary Sudhir
Krishna said there are 11 million
homes that are vacant as per the
latest census figure and out of that
10 per cent lie in the National Capital
Region.
Krishna said the Centre is revisiting
rental law to boost housing supply. He
suggested that real estate projects,
whether built by government bodies
or private developers, should be
handed over to local municipalities
for maintenance purpose.
The Centre had projected total
housing shortage in the country at
18.78 million in the beginning of the
12th Five-Year Plan (2012-17). More
than 90 per cent of shortage exists
for the EWS/LIG section of society.
Expressing concern over the slow
pace of urbanization, he said at least
70 per cent of the population should
live in urban area. “We have not
urbanized enough. The urbanization
level of 31 per cent is not enough. It’s
a serious issue,” Krishna said, adding
that slow pace of urbanization is
putting huge pressure on rural land,
which is resulting in fragmentation
of land holdings to the disadvantage
of farmers.

Waterproofing systems
Inpresent-dayconstructionordinary
portland cement and its blends with
puzzolonic and slag materials have
come to stay. A lot of compatible
alternatives are available for a builder
to choose from various waterproofing
systems. Some systems are old
and conventional, but still practiced
successfully. Some modern systems
take material and structural behaviour
into consideration.
There are some compounds which
are used in plastic concrete to make
it less permeable to water. These
are known as integral waterproofing
compounds. They are based on
plasticising and air-entrainment or
water repellence principles.
These are used as a good
waterproofing precaution when other
factors such as good mix-design,
proper mixing/placing, compacting/
curing, etc are taken care of. There
are some waterproofing techniques
for vertical surfaces. These are also
used for preserving heritage buildings
by stopping/minimizing the aging
process.
Old waterproofing systems
Brick bat coba system or lime
terracing; bituminous treatment;
metallic sheet wrapping; poly-
urethane-based waterproofing
treatment; epoxy-based waterproofing
treatment, box type waterproofing
system, etc.
Brick bat coba system
It was developed during the initial
stages of flat roof construction with
lime mortar burnt clay brick pieces.
This involved laying lightweight mortar
on the roof and spreading it to give
gentle slopes for draining away
rainwater immediately.
The mortar consisted of lightweight
brick pieces as aggregates and
ground brick with lime as binding
matrix. During British rule this system
became more popular, not because
of its waterproofing efficiency, but
because of its efficiency in keeping
interiors cool. Some applicators
developed better skills in laying these
systems, with neatly finished top with
lines engraved on top of plastic mortar
now known as IPS.
Some practiced embedding broken
tile or ceramic pieces in plastic mortar
and called it china mosaic. This type
of system remained most popular with
multi-storey construction in all major
cities. The system lasts up to 15 years
if done by skilful applicators.
Once water starts entering brick
bat coba, brick pieces absorb too
much of water and the roof becomes
an invisible pond of water continuously
causing leakage and increasing
burden on the roof slab. It will be highly
beneficial if brick bat coba is laid on
a flexible waterproofing membrane as
waterproofing as well as economical
weather-proofing can be achieved
with this system.
Bituminous treatment
Bitumen is more commonly used in
the form of felt or flexible membrane
formed by sandwiching jute fabric or
fibreglass/polypropylene mats with
chemically modified bitumen. These
membranes are laid on the roofing
over a bitumen primer.
There are two types of membranes
one is cold-applied and the other
hot-applied, which means one needs
to heat the edges of the felt with a
torch so that they melt and stick to the
second layer in the overlap area.
On the RCC flat roofs the bitumen
feltshavenotbeensuccessfulbecause
of the unacceptable black appearance
and inaccessibility of the terrace for
other social uses. Technically it is not
preferred because bitumen layer or
felt on the terrace not only makes it
watertight but also airtight.
Concrete has breathing property.
It takes water/moisture and breathes
out water vapour. Hindrance of
this breathing property of concrete
develops pore pressure, which causes
blisters in the felt.
After a few seasons the blisters
multiply and eventually delaminate
the felt from the concrete surface.
Hindrance of breathing property of
concrete makes concrete weak. But
on asbestos cement sheets and
zinc sheets in factory roofs, this
bitumen felt is the only dependable
waterproofing system. Hence all
factory roofs in India adopt this water
proofing system. Moreover, bitumen
is the most economical product
available for waterproofing.
Box type waterproofing
This type of waterproofing system is
used only for basement waterproofing
or waterproofing structures below the
ground level from outside to prevent
leakages of subsoil water into the
basement.
In this method limestone slabs
(Shahabad stones) are first laid in the
excavated pit over blinding concrete
in a staggered joint fashion to avoid
the continuity of the mortar joints.
The joints are effectively filled with
rich mortar admixed with integral
waterproofing compound and cured.
Over this the raft is laid and shear/
brick walls constructed. The limestone
slabs are erected around the walls in
a similar fashion leaving a gap of one
to two inches between the external
surface of the wall and the inner face
of the stone surface.
The joints again effectively sealed
with rich admixed mortar and the same
mortar is filled in the gap between the
wall and the stones. This stonework is
continued up to ground level. In this
system the raft and the sidewalls are
protected from direct exposure to sub
soil water.

The Jawaharlal Nehru Port Trust
(JNPT), in association with the National
Highways Authority of India (NHAI)
and the City Industrial Development
Corporation of Maharashtra Ltd
(Cidco), is working on a Rs 1,800-
crore road project to provide seamless
connectivity for trucks coming from
three national highways to the port
and vice versa.
“The plan is to make our existing
43 km of road network which connects
JNPT to three major highways
(Mumbai-Pune, Mumbai-Goa and
Mumbai-Agra) from the present four
lanes to 12 lanes with two lanes
on each side dedicated for public
transport. About Rs 1,800 crore will be
invested in this project on BoT basis.
We have already invited the bids,” said
Neeraj N Kumar, Chairman, JNPT.
“We are making this project a traffic

The National Highways Authority
of India (NHAI), after a poor show
in 2013-14, is readying its work
plan for this financial year, one that
reflects the gloom enveloping the
sector. It is planning to award about
2,000 km through cash contracts, or
EPC mode, and is ready with 3,000
km to be bid via the public-private
partnership (PPP) mode.
NHAI officials said they have
informed the highways ministry of
their targets for 2014-15, but awarding
projects on the EPC mode can only
take off if the NHAI is able to acquire
90 per cent of the land. In addition,
the final award on PPP mode would
depend on the market response,
which has been poor of late, and
may need to be converted to the EPC
mode if no bids are received.
“We have had discussions on what
target to fix and it was decided to
keep a conservative estimate since
we would have to answer to the new
government on the results,” said an
NHAI official.
All in all, it might be possible to
award about 5,000 km of projects,
with about 3,000 km from BoT projects
only if appetite of lenders improve,”
said an NHAI official, adding that the
Authority has communicated to the
highways ministry that if PPP projects
have to be converted to the EPC
distribution network, natural gas
network, street lighting and road works
including landscaping of parks and
green areas.
The project covers about 2,400
hectares, almost the entire area of
Zliten city and is scheduled to be
completed in four years.

movement port traffic we are making
provisions for overbridges and grid
separators. Due to this, the cost is
coming very high at Rs 1,800 crore.
Normally, such a road could have cost
Rs 500 crore. We are also envisaging
the future New Mumbai airport. This
road will give last mile connectivity to
the New Mumbai airport. So we are
ensuring that the traffic coming to
the airport does not disturb the port
traffic,” said Kumar.
For this purpose, JNPT, NHAI
and Cidco have formed a Special
Purpose Vehicle (SPV) called JNPT
Road Company Ltd which has invited
tenders from interested parties to build
this road on a BoT (build, operate and
transfer) basis. JNPT, NHAI and Cidco
have 40 per cent, 50 per cent and 10
per cent equity, respectively in the
SPV. The cost of this project will be
recovered by charging toll.

would have to be examined.
The NHAI chief R P Singh has told
the ministry that further allocation of
resources would be required in such a
case and these issues would have to
be presented to the new government
on priority, said people familiar with
the matter.
As per the work plan, the NHAI is
readying about 2,300 km of highway
projects with a total project cost
over Rs 15,000 crore via the EPC
route, and 3,278 km PPP projects
worth over Rs 35,000 crore. The EPC
projects include Rs 996-crore Talcher-
Dubari-Chandikhole and Rs 675-
crore Bijapur-Gulbarga-Homnabad
stretches which had been bid out in
2012-13 on the PPP mode but failed
to get any bidders.
“In recent months, raising equity
for highways PPPs has become
difficult and there are even signs of
declining interest from developers.
Not only are companies hesitant
to bid for new projects, several
existing assets are up for sale. Many
developers are finding it difficult to
fund the entire shelf of projects. They
are resorting to asset sale to fund
new/existing projects,” said Manish
Sharma, Executive Director, Capital
Projects & Infrastructure at PWC.
Jica okays `674-cr loan
for U’khand forest project
TheJapanInternationalCooperation
Agency (Jica) has approved a loan of
about Rs 674 crore for a forest project
in Uttarakhand.
“The agency signed a Japanese
ODA loan agreement with the
Government of India in New Delhi
to provide up to 11,390 million
yen (around Rs 674 crore) for
‘Uttarakhand Forest Resource
Management Project’,” the agency
said in a release. The agreement was
signed on April 11.
The loan at a concessional
interest rate of 0.30 per cent carries a
repayment period of 40 years with a
grace period of 10 years. The project
aims to improve natural environment
and livelihood of people living in
and around the forest areas with
the loan funds used for afforestation
and income generation of local
communities.
In addition, the project will
support implementation of disaster
reconstruction and prevention
measures in the forest area of
Uttarakhand where heavy rains caused
devastating floods and landslides in
June 2013. The executing agency for
the project is the Uttarakhand Forest
Department.
The project is expected to be
completed by March 2022. “The forest
area in Uttarakhand has not only huge
degradation pressure but also suffered
severe damage during the disaster in
June 2013. This project will contribute
to eco-restoration of the forest area
in conformity with improvement of
the livelihood of the communities,”
said the release. The Jica works to
help developing countries become
self-reliant in pursuing their own socio-
economic development.
This system seeks to delay the
occurrence of leakages in basements.
A lot of building structures are
waterproofed by this system.
Modern techniques
Modern technique aims to
understand functional behaviour of
the structure, understand properties of
available materials arrive at a system,
which is best suited for the structure
and incorporate the system at the
design stage only.
A single product or technique is not
usually enough, involvement of various
bodies and techniques in coordination
is essential for making structures
waterproof. For success of any system
the building structure should have
sufficient and efficient control joints if
the slabs dimensions are more than
20 meter in any direction.
Control joints are structural
engineering design features. These
joints are supposed to be designed
and their configuration marked on
drawings and their detailing needs to
be given with respect to waterproofing
system proposed in large buildings.
Modern technique relies basically
on two main waterproofing systems,
which are foolproof and simple.
They are as follows: Crystalline
waterproofing system and flexible
membrane waterproofing system.
Crystalline waterproofing
system
This system involves blocking
water bearing capillaries with
insoluble crystals. This method
is used for waterproofing water-
retaining structures like overhead/
underground water tanks, sunk slabs
of bathrooms and toilets, swimming
pools, basements, terrace gardens
etc. The main product in this system
is a grey or brown-looking powder.
The method of treatment involves
saturating with water the surface to
be treated. Then mixing two and
half volumes of the powder with
one volume of water to form neat
consistency hot slurry.
This slurry is brush applied on
the saturated surface. The active
ingredients in the slurry pass through
water-bearing capillaries and react
with calcium oxide in concrete
to form insoluble crystals, which
effectively block capillaries. Further,
chemical ingredients of the product
remain in concrete to reactivate the
process of crystallisation as and
when a new capillary is developed.
Flexible membrane
The main product used in this
system comprises two components
-- one liquid and the other is a powder
packed roughly in the proportion of
1:4 by weight. The liquid component
is an acrylic emulsion and the powder
component is a polymer-modified
cement with film forming chemicals
and fillers, and some manufacturers
add reinforcing fibres to make the
product extra effective.
These two ingredients, namely the
pre-weighed powder and the liquid,
are mixed together in an uniform
slurry results. This slurry is brush
applied on the roof surface, which
upon drying forms a flexible film.
Since there is cement in this product
its compatibility with concrete is
excellent.
The film further allows the
breathing of the concrete without any
hindrance hence there is no problems
of its de-lamination from the concrete
surface. This film being flexible takes
care of the deflections in the slab and
the movements caused because of
primary or secondary settlements,
movements due to wind loads and
temperature stresses developed
in the concrete. This system can
be used on surfaces, which had
bituminous treatment earlier.
Generally, architects in India, do
not specify in-depth waterproofing
details and leave this aspect generally
to ignorant clients to chose whatever
system he likes, and many structural
designers give least importance to
the control joints. As a result of this,
many systems have failed in several
prestigious buildings and the blame
went to waterproofing contractors or
the product manufacturer.
There is a need for architects and
structural designers to understand
various systems available and specify
them clearly and in sufficient detail,
taking into consideration in-service
conditions of the structure.
The client should also insist on the
architect to provide waterproofing
design details in advance so that no
ambiguity remains till the end. This
would give enough time in selecting
the specified material.

Splendour in
colour concrete
In a part of the world where
impressive buildings are not exactly
thin on the ground, a hotel building
needs to have quite a few special
attributes to make it stand out.
The Emirates Palace in Abu Dhabi
certainly has an awesome number
of those.
The five-star hotel is one of the
largest in the world and offers a whole
range of superlatives. 250,000 cubic
metres of concrete coloured with
Bayferrox® pigments were used to
build the hotel on an area of 243,000
sq metres. 20,000 building workers
were involved in the construction of
the palace.
The giant building has a perimeter
of 2.5 kilometres, and the 40-metre
high archway at the hotel entrance is
taller than Berlin’s Brandenburg Gate.
The inside of the hotel also matches
up to these structural superlatives:
102 elevators take the guests to
the 302 rooms and 92 suites. The
kilometer-long corridors are provided
with several thousand signs to prevent
guests from getting lost.

Traditional oriental patterns have,
with the help of modern technology,
become an integral part of the

What are the reasons for slow
growth of India’s Green real estate
sector? How do you see it at the
policy level (Centre and state)?
India’s Green real estate sector
is witnessing a very healthy growth
rate and the trends are indeed
encouraging and vivid. In the last
week of March 2014, India reached a
remarkable milestone when it crossed
the 2 billion sq ft mark of Green
building footprint registered with
the IGBC, the Indian Green Building
Council. This also propels India
to premier position of the second
largest Green building footprint in
the world.
‘2 b sq ft Green building footprint
registered with IGBC’
“Government should provide more incentives in terms
of higher FAR for Green building projects, reduction
in property tax, faster clearance for Green building
projects and special concessions for Green products
& technologies,” says Dr Prem C Jain, Chairman
of the Indian Green Building Council (IGBC) and
AECOM India in an interview with Paresh Parmar
It is important to note that India
reached the first 1 billion sq ft
milestone in 2011 and in a short
span of only about two-and-a-half
years, it has crossed the 2 billion sq
ft of Green building footprint. This is a
clear testimony that India’s Green real
estate sector is on the boom and is
adding great value to the country.
The Confederation of Indian
Industry (CII) has set targets for
Indian Industries for India@75, which
is 75 years from independence, that
is the year 2022. Therefore, the IGBC
has also announced that India@75
will become Global Leader with 10
billion sq ft of Green buildings.
Today, all types of buildings
all across the country are going
the IGBC way. This growth and
progress has been made possible
with the innovative and inspirational
role of the IGBC and support of
all the stakeholders including
government, developers, architects
and corporates.
Some of the government projects
that are going the IGBC way include:
Police Bhawan, Gulbarga; HUDA-
Annexe-II, Hyderabad; Thyagaraj
Sports Complex, New Delhi;
Jawaharlal Nehru Bhawan, Ministry of
External Affairs, Government of India,
New Delhi; General Pool Residential
Area (GPRA) MoUD, New Delhi; and
Govt. Mohan Kumaramangalam
Super Specialty Hospital & Trauma
Care Centre, Salem, Tamil Nadu.
The IGBC is constantly working
with the Central government and
several state governments to obtain
incentives like additional FAR, lower
power tariff and faster statutory
approvals for Green buildings. This
would provide great impetus to
India’s Green real estate sector to
scale greater and ‘greener’ heights.
How do you see the need for
creating awareness about long-
term benefits of patronizing
Green developments among
consumers?
Sustainable buildings have been a
way of life in India for centuries. All the
ancient structures including temples,
mosques, forts, even ‘havelis’ were
skillfully built, using locally available
resources, and incorporating features
which were in harmony with nature.
Historically, we worshipped the five
elements of nature (Panchabhutas)
and people of all walks of life
practiced austerity in all that they
consumed; these in today’s context
signify ‘Green’. In fact, going the
‘greener’ way is intrinsically imbibed
and part of our ethos.
However, we have drifted away
from our rich and varied heritage
in the past 50 years, blindly aping
Western practices which are not
relevant to our way of life, nor climate,
nor resources. Today, our rivers and
water bodies have been polluted from
effluents from chemical industries
and we have become a water-
deficient country.
The need of the hour is to go
back to our roots and incorporate
the state-of-the-art technologies. With
this objective in India, the IGBC is
partnering with the Resident Welfare
Associations (RWA) and working
closely with owners/occupants in
sensitising them on ‘greener’ way.
The IGBC is promoting and
encouraging the use of BEE star-
rated electrical equipment and
appliances. In order to conserve
water resources, the IGBC is working
with the International Association
of Plumbing & Mechanical Officials
(IAPMO) in developing rating system
for locally manufactured water
efficient fixtures and also sensitising
stakeholders on the urgent need and
importance of ultra-low flow fixtures.
The IGBC celebrates World Green
Building Week in September every
year across the country, highlighting
that Green buildings make better
place to live, work and play, and
they will improve the wellbeing and
quality of life for everyone in the
community.
Therefore, today going the
‘greener’ way is an imperative for
a sustainable tomorrow. This is
good both for preserving life on
our beautiful planet earth and for
our country’s economy. The adage
‘Little drops of water make a mighty
ocean’ may seem clichéd, but is
very applicable in this case. Small
but significant steps are the need of
the hour.
Can you elaborate on measures
that would assist the growth of
Green real estate sector in India?
As a result of the concerted efforts
of the IGBC, today India is one of the
global leaders in Green buildings.
For instance, in 2003, there were
very few products and employment
opportunities in this sector.
However, with the awareness
created by the Green building
movement across the country, the
sector has witnessed tremendous
growth opportunities. We still have a
long way to go.
To further accelerate the growth
and spread of the sector, concerted
efforts should be undertaken to
further generate awareness on the
urgent need and importance of Green
buildings.

Consumers should demand for
high performance Green building
products & technologies. They
should enquire on the extent of the
recycled/recyclable content of the
product used in construction of
their building. This in turn will trigger
more demand for Green products &
technologies. They should not settle
for anything less than a certified and
fully functional Green building.
All the upcoming buildings across
the country should be conceived,
designed and constructed as per
Green building norms. This will provide
new avenues to develop products &
technologies which are ecologically
superior and economically viable for
our needs.
Government should provide more
incentives in terms of higher FAR for
Green building projects, reduction
in property tax, faster clearance for
Green building projects and special
concessions for Green products &
technologies.
C o n c e r t e d e f f o r t s b y a l l
stakeholders would go a long way
in further accelerating the growth of
Green real estate sector in India.
Tell us about your outlook for the
industry.
The outlook for the industry is
very promising and encouraging. In
the next two decades, India would
be witnessing huge demand for
residential spaces, commercial
buildings, schools, infrastructural
projects, hospitals, and other
applications.
It is estimated that about 70 billion
sq ft of building footprint would be
added in the next
two decades in India. Hence,
there exists a huge opportunity in the
design & construction of all upcoming
buildings as Green buildings. The
buildings can be designed as Green
right from day one.
India will have more of Net-zero
(energy & water) buildings and as
a result it will effectively manage
its energy & water requirements.
The optimized resources can be
channelized to other resource crunch
areas.
The IGBC foresees that the next 10
years will be the decade of integrated
sustainable built environment. This
will mostly be in the form of large
integrated townships, satellite cities,
gated communities, and campuses
with multiple buildings. This presents
an enormous opportunity to design
these developments as Green and
influence the lifestyle of people
who live in such cities. The need to
promote Green cities becomes an
imperative.
Another important outlook in the
sector would be the active involvement
of the younger generation in further
Greening India. Green schools and
educational institutes will be spread
across the country.
Generation of power from new
and renewable energy sources such
as wind, mini hydro, biomass and
solar energy will receive increased
impetus. Green will become the way
of life.
How do you see the opportunity
ahead in converting existing
buildings into green?
India today has over 30 billion sq
ft of existing building stock. Energy
cost (electricity, DG & fossil fuel)
alone is estimated to be around 60
per cent of the total operation and
maintenance cost (including energy,
water, repairs, etc) in existing building
stock. Therefore, it is imperative to
explore the scope for reduction in
their energy consumption through
building envelope optimization, and
upgrading air- conditioning, plumbing
& lighting technologies.
Green practices in the existing
buildings can help address national
issues like water efficiency, energy
efficiency, reduction in fossil fuel use
in commuting, handling of waste and
conserving natural resources. The
operational savings through energy
& water efficiency alone could range
from
15-30 per cent. Most importantly,
these concepts will enhance occupant
health, happiness and well-being.
In light of this, the IGBC with
the support of all stakeholders has
launched in April 2013 at Mumbai,
India’s first Green Building Rating
System for O&M of Existing
Buildings.
The overarching objective of this
rating tool is to facilitate building
owners and facility managers in
implementation of Green strategies,
measure their impacts and sustain
the performance in the long run.
The thrust is on implementation and
results achieved.
The pilot version of IGBC Existing
Buildings O&M rating system is
applicable for all types of non-
residential buildings, including
office buildings, IT parks, BPOs,
shopping malls, hotels, hospitals,
airports, banks and other commercial
applications.
Building types such as industries,
factories, educational institutions
and schools will be covered
under respective IGBC rating
programmes.
Buildings which are 80 per cent
occupied (with respect to the carpet
area,) and operational for a minimum
of one year, are eligible for certification
under the IGBC Existing Buildings
O&M rating.
Projects already certified and
operational for more than one year
are also eligible to apply for the IGBC
Existing Buildings O&M certification
This rating is evoking excellent
response from stakeholders. Already
10 existing building projects,
amounting to over 2 million sq ft
are registered with the IGBC under
this rating.
For instance, Bombay House,
the headquarters of Tata Group, has
become the country’s first existing
building to get the prestigious Green
gold rating from the Indian Green
Building Council (IGBC).
Some of the key Green features of
Bombay House -IGBC gold certified
existing building include:
Energy savings of more than 20
per cent.
Renewable Energy Certificates
(REC) equivalent to more than 75 per
cent of annual electricity consumption
requirement of the building have
been purchased by owner.
Water savings of more than 50
per cent.
Bombay House, for the whole year
of 2013, has achieved an Energy
Performance Index (EPI) of 124.96
kWh/m2/year. Efforts are to have EPI
further go down to below100 kWh/
m2/year.
The success story on Bombay
House is a clear testimony that
if a 90 year old heritage building
can obtain Gold EB rating, there is
every possibility that more recently
constructed existing buildings can
go the ‘greener’ way.
The ‘greening’ of existing buildings
also offers immense untapped market
opportunities. It is estimated that by
2025, the Retrofit Potential of Existing
Buildings in India would be about
$25 billion.
We are confident that in days to
come, many more existing building
will go the ‘greener’ way and play an
important role in facilitating India to
emerge as one of the global leaders
in Green buildings by 2025.
What are the measures taken and the
role of the IGBC towards achieving
common goal of sustainability?
TheIGBCoperatesonaconsensus
based approach and it is a member-
driven organization. The IGBC, with
the support of stakeholders, has
addressed the following 3 A’s:
Awareness on the need and
importance of Green buildings
Availability of Green building
products and technologies
Affordability of Green building
products & services
A vast majority of key stakeholders
of the construction industry in India
are part of the Council. Currently,
the Council has its membership
strength of over 1,675 registered
organizations. The IGBC adopts the
following multi-pronged strategy
towards achieving the common goal
of sustainability.
Launch of IGBC local chapters:
These chapters work closely with
all stakeholders in the region, and
spread awareness of the Green
building concepts at the state and
regional levels. The IGBC currently
has launched 15 local chapters
across the country, 3 more are in
the offing.
Further,theIGBCworkscloselywith
various Central and state government
departments in highlighting the
urgent need and importance of Green
buildings. As a result of concerted
efforts, the IGBC could facilitate the
following:
The Ministry of Environment &
Forests, and the Government of India
accord faster clearances for projects
applying for the IGBC Green Building
Certification
New Okhla Industrial Development
Authority (Noida) provides higher
FAR (5 per cent) to Green building
projects.
A s s i s t a n c e w i t h d r a f t i n g
of environmental guidelines for
Maharashtra
Green guidelines for existing
& new factory buildings in Andhra
Pradesh
The Hyderabad Metropolitan
Development Authority (HMDA) offers
Green channel for Green buildings
Kerala state PWD has issued
directive that all state government
buildings in Kerala will be IGBC
certified.
Further, the IGBC’s flagship event
and India’s largest conference with
exhibition on Green buildings. This
provides a unique platform to learn,
share and explore new business
opportunities. The 12th edition of
Green Building Congress 2014 is
scheduled to be held on September
4-6, 2014 at the International
Convention Centre in Hyderabad.
We regularly organize training
programmes across the country to
share information on Green building
concepts, on IGBC Green Building
rating systems and to share best
practices in Green buildings.
We have set up a Green technology
centre which is housed in the CII-
Godrej GBC building, India’s first
Platinum-rated Green building. It
serves as a platform to showcase
Green products/technologies and
also enables visitors to have a
touch & feel of the innovative Green
products under development.
Moreover, the IGBC forges vibrant
partnerships with various national
and international organizations in
exploring new areas of cooperation
and business opportunities. Some
of the recent MoUs inked by the
IGBC include MoU with NHB, Credai,
the University of Salford, IAPMO,
ASHRAE India, ISHRAE and IPA.
The IGBC in its efforts to reach
the student community has launched
over 40 student chapters across the
country. These chapters aim to instil
a sense of commitment towards
Planet Earth and encourage student
members to adopt the ‘greener’
way.
The IGBC also regularly organizes
‘Paint our Earth- Drawing Competition
for Schoolchildren’, aiming to generate
awareness amongst schoolchildren
on the need and importance of
environmental protection.
Any message to the industry?
The IGBC, with the support of
all stakeholders, has successfully
demonstrated an excellent business
case for construction of Green
buildings. Today, constructing Green
buildings is technically feasible and
economically viable, and India is well-
poised to be the global leader in the
Green building movement.
The Green building sector in India
offers immense untapped market
opportunities.
A study conducted by the IGBC
indicates that the market potential
for Green building products and
technologies would be about $120
billion by 2015. India is well-poised
to develop more of innovative and
futuristic materials and technologies
which are not only eco-sensitive and
energy-efficient, but will significantly
address the fast depleting resources
and play a catalytic role in preserving
and protecting our Planet Earth.
The place we live, work, study,
play should all go the ‘greener’ way.
Therefore, partner with the IGBC in
making Greener India.

The main reasons
for water leakages
are water stagnation,
inadequate slope for
drainage of rainwater
and deterioration of
waterproofing system
leakage through walls between units
of pre-fabricated elements.
Leakage from metal pipe
surfaces
Seepage through defective joints
or pipes caused by poor installation
or differential movements and
settlements are the main causes
of water leakage from metal pipes.
Corrosion of metal pipes at junctions
with floors or walls, invasion of water
into conduits, blockage in pipes
leading to excessive pressure built
up or sometimes attack by rodents
or roots of plants causing damage of
metal pipes and leakage occurring at
these locations.
In case of exposed supply pipes
or drains there may be inadequacy in
design of drains such as insufficient
diameter, bends being too sharp,
etc. Also, blockage of drains at the
junction of bends or traps, open joints
such as hoppers of down pipes may
lead to leakages of water.
Musty smell coming from the
basement may be subtle, but grows
Sources and solutions to leakage
Water seepage occurs mainly
from external walls, windows, roof
or the ceiling which may cause
water staining, peeling off of paint or
wallpaper, water dripping, growth of
fungus, defective concrete, plaster or
tiles and rust staining.
This could be due to a variety of
reasons. They are common defects in
causing nuisance to occupiers across
floors. It is sometimes very difficult
to identify the source or cause of
water seepage for which an extensive
investigation may be necessary.
Many homeowners often ask
for a list of warning signs of water
leakage and damage. Such queries
come more often in cities that endure
excessive rainfall, prolonged rainy
season such as Mumbai.
It is extremely important in such
places to have a list as a guide for
self-inspection in the hope that they
might have an early detection of
problems and consequently their
timely redressal. A tentative checklist
is given below for a ready reference.
Leakage from roofs
The main reasons for water
leakages are water stagnation,
inadequate slope for drainage of
rainwater and damage or deterioration
of waterproofing system. Leakage
occurs through pores and connected
capillaries in concrete structures,
thereby corroding reinforcement.
Sometimes a defective enclosure
for water tanks, cracks of parapet
walls affects waterproofing systems.
Inadequate protection of roof slab or
improper installation of waterproofing
system may also lead to leakage.
Leakage through windows
This may be due to forming of
gaps between window frame and
masonry, between lintel beam and
masonry, and through alumimium
frame and window sill which can be
avoided by choosing and sealing with
a right kind of sealant.
Leakage from internal
wet areas
Leakage from bathrooms or
kitchens is usually caused by seepage
from fitments, bathtubs, shower
trays, buried pipes or drains due to
improper construction of joints and
improper installation of sealants.
The inadequate slope of such floors
may lead to water stagnation for some
time due to which water may penetrate
through tile joints. Waterproof cement
rendering underneath floor tiles for
the floor not installed properly and
improper installation of sockets or
conduits are some of other causes
of bathroom leakage.
Damp patches on dry walls
Water penetration takes place
through external wall defects such as
hairline cracks, joints, honeycombs,
spalling, weak points, holes, punctures
and leftovers of debris. The hairline
cracks begin to grow further and allow
seepage of water.
The movement of external wall
components leads to settlement
cracks on the wall. Also, water
penetration takes place through
defective external wall finishes such
as loosened mosaic tiles, cracked
ceramic tiles and paint surface, poor
cladding or curtain walls constructions.
Another cause may be due to water

draperies.
Many of these signs become visible
only after leakage and damage to the
basementreachacriticalstage.Itisbest
to inspect early and often. If any of these
signs are visible, call in a professional
waterproofing agency. Remember that
water damage creates problems not
only to your house, but it additionally
causes various health issues.
If you are serious about your
property, you should attend to any
leakages from plumbing and drainage
line immediately to prevent damages
to wall and structure. Terrace should
be cleaned every month. All bathroom,
water closet and kitchen traps are
vulnerable areas that demand careful
and frequent check. All cracks on
external walls should be inspected
and repaired as soon as detected.
Points to remember
It should also be borne in mind it
is essential to:
Avoid nailing at parapet or any
external surface
They are time-consuming and
cumbersome jobs and looking
at modern era of time-bound
construction projects, they are not
the right choices.
Climatic changes and weathering
effects are the major issues for non-
acceptability of these techniques.
Finally, specifically the brick bat
coba is technically not a waterproofing
solution as the porous bricks and
in-filling mortars used for such
techniques absorb a large amount
of water inside the system.
Though the brick bat coba is
advantageous to build up the slope
on flat roofs, it also adds dead load on
the slab structure. Moreover, in case
of existing roofs with brick bat coba,
it is very difficult to find out the actual
source of water ingress which in turn
challenges rehabilitation work.
New generation techniques
Polymer science has created a new
dimension to waterproofing solutions
to building structures and today a
plethora of waterproofing materials
Specialized polymeric crack filling
material or polymer mortars should
be used to fill up those areas and
the external faces to be covered with
weather resistant protective coatings
rather than decorative finish paints.
Vegetation growth also plays a
vital role in bringing external moisture
inside the building elements through
their roots, stems and leaves. Removal
of such unwanted vegetation along
building facades and subsequent
filling of gaps with moisture insensitive
polymeric mortars would be the right
choice.
Basements, foundations
Another very important issue
is concerned with the design of
basements and foundations
depending on their usage like car
parking, commercial establishments,
storages, workshops and in various
demands as applicable in case to
case basis.
Basements being the closed
areas are very prone to high humid
conditions leading to dampness
stronger.Thismaybeduetoinadequate
or damage of tank waterproofing
systems (due to movements or
punctures) and also may be due
to deterioration of water stops at
construction and movement joints.
Growth of mould, mildew and
fungus inside the building. All these
become visible after colonization of
spores and showing discoloration
of paints and coatings and creating
unhygienic atmosphere inside
buildings.
Peeling of paint from
wood surfaces
If there are wood surfaces, paint
begins to peel off from window
frames, doors and other surfaces. This
may happen due to improper fillings
around frames and deformation of
frame and sashes, defective gasket,
sealant or putty for window glass
setting or frames.
The other factor which may lead to
wood surface due to moisture ingress
may be due to air- conditioning box or
platform tilting inwards or insufficient
sealant around air-conditioning units.
The other causes are growth of
vegetation, ingress of water through
the joints. The signs of distress may
be observed from the appearance of
powdery substances on furniture and
Never overload ‘chhajja’ with

Traditional techniques
Waterproofing in our country is
being done over several years by
various conventional and traditional
methods such as:
Lime terracing for roofs
Brick bat coba for roofs and
terraces
Mud fuska for roof surfacing
Shahabad tile finishing for
basements and retaining walls
Box type waterproofing techniques
for basement
The methods are used over a
period of time. But they have certain
limitations and disadvantages. To
mention some herewith:
As all the methods are labour-
intensive, scarcity of skilled labour
in today’s construction industry is
one of the major drawbacks of these
methods.
as per international standard are
available. The only requirement is that
we should focus leakage problems
in a comprehensive way and try to
resolve them with a proper scientific
approach.
For example, leakage from flat
roofs could be due to water stagnation
and subsequent percolation of water
through cracks on surfaces or in
parapet walls. Such a problem can
be solved building a proper slope
and repairing the cracks with suitable
crack-filling materials.
Similarly, if joints in external
facades between window frames
and masonry walls or gaps between
aluminium frames and window can
still be taken care of with proper
elastomeric sealant, the ingress of
water can be restricted.
Leakages in bathrooms and wash
areas can be resolved by following a
proper waterproofing specification
while casting the sunken slab followed
by filling of gaps and joints on floors,
plumbing lines and internal fittings
with sealing materials.
Vegetation growth
Penetration of water through
external walls normally takes place
through hairline cracks, joints,
honeycombs, holes and punctures.
and flooding which in turn damage
structures. The other critical factors like
varying water level subjected to tidal
situations and monsoon rain intensity
coupled with blocking of sewerage
pipelines intensify leakages. A more
detailed solution like tanking with a
water barrier membrane coupled with
effective drainage system should be
envisaged.
Cost comparisons
The polymeric waterproofing
techniques vary in their characteristics
and application techniques,
depending on the usage areas.
Henceforth, the cost implication is
also multi- faceted ranging between
arbitrary numbers.
The initial cost of application may
be a little high, but the advantageous
part is the speed and ease of
application coupled with long term
durability and service life compared
with conventional techniques.

As per feedback from end-users
CCMA introduces technical training
programmes to build skills for
applicators, which is key to success
for any waterproofing and protection
systems. Accordingly about four
regional seminars are planned by the
association.
The association has planned
a Handbook on Admixtures in
collaboration with Indian Concrete
Institute. Further, the association is
attempting to introduce technical
topics in the academic syllabi.
Training programmes are at an
advance stages.
With all this, the association feels,
the industry is confident of growing
from present revenue of about Rs
3000 crores to Rs 5000 crores in
the next 2-3 years. This is absolutely
possible considering the large gap in
demand and supply.
This growth is totally dependent on
government accepting construction
chemicals as recognised industry.
With the recent success of CCMA’s
C3 event the association is confident
of future prospects and has planned
the next edition of this event in
Kolkata during February 2015.
