Below-ground waterproofing
For below-ground structures where the exterior face of the structural concrete is inaccessible, the waterproofing must be applied
prior to pouring the concrete. Conventional systems are either loose-laid or self-adhering to the substrate not the structural
concrete, this means there is no seal between the waterproofing and the structural concrete which can lead to water travelling
between the waterproofing and the structure from any leakages that may occur. BS 8102:2009 highlights this problem and
recommends that a fully-bonded pre-applied waterproofing system be used to mitigate this risk. A similar problem occurs where
ground settlement takes place. BPA has developed an innovative system, DualProof, which incorporates a unique FiberTex-fleece.
The DualProof membrane is installed with the "FiberTex" non-woven fleece facing the concrete which is to be waterproofed.
The fleece mechanically bonds to freshly placed concrete giving a unique waterproof seal, preventing any lateral water migration.
It is installed rapidly with no need for blinding concrete, priming or protection and can be trafficked immediately after application. It
is Radon Gas resistant and highly durable and is unaffected by contaminants within the ground. Quality is assured through MPA,
KIWA, DIN EN 13967, CE-Certification, DIN V 20000-202 and DualProof is suitable for use in accordance with SIA, DIN and BS.
•	 installation - no blinding concrete or
protection required.
•	 Assured watertight integrity - overbridges cracks
Mechanical bond to the fresh concrete
•	 No water-tracking - improoving concrete strength
•	 Easy jointing independent of temperature
-working temperature -5 up to 45 degree Celsius
•	 Integrity assured at pile caps
•	 Excellent solution for insitu concrete.
•	 Protects structure against ground
contaminants and slat water
•	 Long term watertight durability
The actual BS 8102:2009 standard for waterproofing below-ground structures, gives
recommendations and provides guidance on methods of dealing with and preventing the
entry of water from surrounding ground into a structure below ground level. Designers are
encouraged to follow a process chart, to ensure that the correct waterproofing system will be
selected. Some of the recommendations are highlighted below;
•	 To help mitigate risk, specify a combination of various types of compatible protection
sourced from the same manufacturer -- BPA combines Type A and Type B waterproofing
•	 Where a waterproofing barrier is required for a structure supported on piled foundations,
special consideration should be given to the detailing so that structural continuity is not
compromised.
•	 Strategies for dealing with groundwater, soil gases and contaminants should be
considered from the earliest stages of the planning and design processes.
•	 Products that are both water and gasproof are more cost-effective. DualProof is Radon-tight!
•	 Where waterproofing admixtures are used, these should be in conjunction with other
waterproofing components supplied by the same manufacturer, e.g. waterstops,
membranes and sealants.
•	 Fully bonded systems allow potential defects to be located and made good more easily.
•	 Each project structure should be designed to its particular Grade
BS 8102:2009, DIN, SIA
Grade Example of use of structure Performance level
1 Car parking; Plant rooms
(excluding electrical equipment);
Workshops.
Some seepage and damp areas
tolerable, dependent on the intended
use.
Local drainage might be necessary to
deal with seepage.
2 Plant rooms and Workshops
requiring a drier environment (than
grade 1); Storage areas.
No water penetration acceptable.
Damp areas tolerable; ventilation might
be required.
3 Ventilated residential and
commercial areas, including
offices, restaurants etc ; Leisure
centres.
No water penetration acceptable.
Ventilation, dehumidification or air
conditioning necessary, appropriate to
the intended use.
One, or a combination, of the following types of waterproofing protection should be selected:
Type A – (barrier) protection
Protection against water ingress which is dependent on a separate barrier system applied to
the structure. e.g. DualProof, SilverSeal or CEMtobent
Type B – (structural integral) protection
Protection against water ingress which is provided by the concrete structure.
e.g. CEMflex-Admixtures in conjunction with Predimax, CEMswell, Quellmax, CEMflex
Type C – (drained) protection
Protection against water ingress into usable spaces which
is provided by the incorporation of an appropriate internal
water management system. e.g. CEMdrain
DualProof is the professionals choice for fully-bonded Type A barrier protection for below-ground
structures to achive a basement Grades 1, 2 + 3 as described in BS 8102:2009. It is fully compatible
with the BPA CEMdrain drainage and protection board and the CEMflex liquid waterproofing concrete
admixtures assuring best system performance which may be sourced from one premium supplier.

In the unlikely event of damage to the membrane during
installation, the smart anti-tracking Fiber-tex fleece of DualProof
will prevent any water tracking between the membrane
and the concrete.
DualProof has been tested to ASTM D5385 and
shows no lateral water migration when tested at 50m
hydrostatic water pressure. (University of Nuernberg GER)
The FiberTex Fleece has a positive influence of the water/
cement ratio in the concrete cover zone and improves
the quality of the concrete surface on the very best way.
Non water-tracking

DualProof - Fresh Concrete Bonding Waterproofing Membrane
The transparent membrane allows to assess the concrete quality.
It is possible to examine the concrete finish through the installed
membrane after the form-work has been removed.
DualProof will remain in place fully bonded
to the structural concrete assuring complete waterproof
integrity even if ground settlement or concrete cracks occurs.

Blinding concrete is preferred,
however DualProof can be
placed directly on top of a well
compacted smooth granular fill
substrate. A broadcast of damp sand
on top of the granular material is
useful.
Removal of the blinding concrete
means less concrete and less labour
time but also means less concrete
truck movements which not only
saves time and money but is more
environment friendly.
DualProof is a robust, heavy
duty membrane with many refererences
in projects throughout the world.
The structural steel reinforcement is
laid directly on top of the membrane
ready for the structural concrete
placement.
There is no requirement for screed
protection which saves valuable
time and money.
An ever increasing level of importance is being placed by owners and designers
with regards to structural integrity, cost-effectiveness and durability. BPA
recognise this, and DualProof with its proven history, excellent holistic
cost benefits and independent certification offers an unparalleled system
solution for below-ground structures to combat these demands. It provides
owners, clients and designers with a high performance system backed by
excellent customer/technical service delivered through a comprehensive
international network.
DualProof is designed for typical site conditions. It is heavy duty, robust
and can be rapidly installed with easy to apply jointing ancillaries which are
system-compatible. The system has a long track record, however BPA
can offer on-site training assistance for specific projects, delivered through
teams of local experts. Contact your BPA office for more details.10 11

Our range BPA’s range of waterproofing and concrete construction products include engineering and architectural waterproofing, concrete technology, concrete sealing, jointing systems, sealants, waterproofing materials, waterproofing membranes, bentonite based sealing systems, bentonite double sealing membranes, pre-applied concrete bonding membranes, self-healing membranes and water stops. The DualProof waterproofing system is proven technology and has successfully waterproofed many below-ground concrete structures since its launch. It can be found in projects in many countries around the world and is quite simply one of the best performing cost-effective below-ground waterproofing solutions available today. Brochure contents • Innovative Technology • BS 8102:2009, DIN 18195 T6, DIN V 20000-202 • The benefits of using DualProof • Typical applications • A system-based solution DualProof waterproofing membrane 2 3 The most innovative medium-sized businesses
  • 3. Innovative anti-tracking, pre-applied waterproofing system The solution that stands the test of lifetime Concrete Walls Under-Slab Pipe Penetration4 5
  • 4. Below-ground waterproofing For below-ground structures where the exterior face of the structural concrete is inaccessible, the waterproofing must be applied prior to pouring the concrete. Conventional systems are either loose-laid or self-adhering to the substrate not the structural concrete, this means there is no seal between the waterproofing and the structural concrete which can lead to water travelling between the waterproofing and the structure from any leakages that may occur. BS 8102:2009 highlights this problem and recommends that a fully-bonded pre-applied waterproofing system be used to mitigate this risk. A similar problem occurs where ground settlement takes place. BPA has developed an innovative system, DualProof, which incorporates a unique FiberTex-fleece. The DualProof membrane is installed with the "FiberTex" non-woven fleece facing the concrete which is to be waterproofed. The fleece mechanically bonds to freshly placed concrete giving a unique waterproof seal, preventing any lateral water migration. It is installed rapidly with no need for blinding concrete, priming or protection and can be trafficked immediately after application. It is Radon Gas resistant and highly durable and is unaffected by contaminants within the ground. Quality is assured through MPA, KIWA, DIN EN 13967, CE-Certification, DIN V 20000-202 and DualProof is suitable for use in accordance with SIA, DIN and BS. • installation - no blinding concrete or protection required. • Assured watertight integrity - overbridges cracks Mechanical bond to the fresh concrete • No water-tracking - improoving concrete strength • Easy jointing independent of temperature -working temperature -5 up to 45 degree Celsius • Integrity assured at pile caps • Excellent solution for insitu concrete. • Protects structure against ground contaminants and slat water • Long term watertight durability The actual BS 8102:2009 standard for waterproofing below-ground structures, gives recommendations and provides guidance on methods of dealing with and preventing the entry of water from surrounding ground into a structure below ground level. Designers are encouraged to follow a process chart, to ensure that the correct waterproofing system will be selected. Some of the recommendations are highlighted below; • To help mitigate risk, specify a combination of various types of compatible protection sourced from the same manufacturer -- BPA combines Type A and Type B waterproofing • Where a waterproofing barrier is required for a structure supported on piled foundations, special consideration should be given to the detailing so that structural continuity is not compromised. • Strategies for dealing with groundwater, soil gases and contaminants should be considered from the earliest stages of the planning and design processes. • Products that are both water and gasproof are more cost-effective. DualProof is Radon-tight! • Where waterproofing admixtures are used, these should be in conjunction with other waterproofing components supplied by the same manufacturer, e.g. waterstops, membranes and sealants. • Fully bonded systems allow potential defects to be located and made good more easily. • Each project structure should be designed to its particular Grade BS 8102:2009, DIN, SIA Grade Example of use of structure Performance level 1 Car parking; Plant rooms (excluding electrical equipment); Workshops. Some seepage and damp areas tolerable, dependent on the intended use. Local drainage might be necessary to deal with seepage. 2 Plant rooms and Workshops requiring a drier environment (than grade 1); Storage areas. No water penetration acceptable. Damp areas tolerable; ventilation might be required. 3 Ventilated residential and commercial areas, including offices, restaurants etc ; Leisure centres. No water penetration acceptable. Ventilation, dehumidification or air conditioning necessary, appropriate to the intended use. One, or a combination, of the following types of waterproofing protection should be selected: Type A – (barrier) protection Protection against water ingress which is dependent on a separate barrier system applied to the structure. e.g. DualProof, SilverSeal or CEMtobent Type B – (structural integral) protection Protection against water ingress which is provided by the concrete structure. e.g. CEMflex-Admixtures in conjunction with Predimax, CEMswell, Quellmax, CEMflex Type C – (drained) protection Protection against water ingress into usable spaces which is provided by the incorporation of an appropriate internal water management system. e.g. CEMdrain DualProof is the professionals choice for fully-bonded Type A barrier protection for below-ground structures to achive a basement Grades 1, 2 + 3 as described in BS 8102:2009. It is fully compatible with the BPA CEMdrain drainage and protection board and the CEMflex liquid waterproofing concrete admixtures assuring best system performance which may be sourced from one premium supplier.

  • 6. In the unlikely event of damage to the membrane during installation, the smart anti-tracking Fiber-tex fleece of DualProof will prevent any water tracking between the membrane and the concrete. DualProof has been tested to ASTM D5385 and shows no lateral water migration when tested at 50m hydrostatic water pressure. (University of Nuernberg GER) The FiberTex Fleece has a positive influence of the water/ cement ratio in the concrete cover zone and improves the quality of the concrete surface on the very best way. Non water-tracking DualProof benefits Permanently bonds to structural concrete No blinding concrete required No membrane protection required Benefits to owners / designers Benefits to contractors / installers DualProof - Fresh Concrete Bonding Waterproofing Membrane The transparent membrane allows to assess the concrete quality. It is possible to examine the concrete finish through the installed membrane after the form-work has been removed. DualProof will remain in place fully bonded to the structural concrete assuring complete waterproof integrity even if ground settlement or concrete cracks occurs. Made in Germany High Quality - ISO 9001:2008 TÜV-Süd Germany Dual Proof fulfills DIN EN 13917 - CE Certification BS 8102:2009 Type A, DIN 18195 T6, SIA 272 Tanking system with the total security Aging Test completed - German Radon Gas test passed Very good mechanical bonding to the concrete Quality - Technology - Waterproofing - German Engineering Blinding concrete is preferred, however DualProof can be placed directly on top of a well compacted smooth granular fill substrate. A broadcast of damp sand on top of the granular material is useful. Removal of the blinding concrete means less concrete and less labour time but also means less concrete truck movements which not only saves time and money but is more environment friendly. DualProof is a robust, heavy duty membrane with many refererences in projects throughout the world. The structural steel reinforcement is laid directly on top of the membrane ready for the structural concrete placement. There is no requirement for screed protection which saves valuable time and money. An ever increasing level of importance is being placed by owners and designers with regards to structural integrity, cost-effectiveness and durability. BPA recognise this, and DualProof with its proven history, excellent holistic cost benefits and independent certification offers an unparalleled system solution for below-ground structures to combat these demands. It provides owners, clients and designers with a high performance system backed by excellent customer/technical service delivered through a comprehensive international network. DualProof is designed for typical site conditions. It is heavy duty, robust and can be rapidly installed with easy to apply jointing ancillaries which are system-compatible. The system has a long track record, however BPA can offer on-site training assistance for specific projects, delivered through teams of local experts.
