2. WELCOME TO OUR PRESENTATION ON
TEXTILE IN BUILDING TECHNOLOGY & ROAD
CONSTRUCTION

3. INTRODUCTION
Textile is no more used only for interior applications like carpets & curtains
but used in civil engineering for temporary structures. New textile materials
invention & methods textile are used in permanent applications of houses &
civil engineering. Current era we are more focused in construction, houses &
building design have more sunlight, greener, high performance, cost saving
& sustainable structure. To fulfill that requirements textile play a
fundamental role.
Textile used in
Build tech,
Geotextile,
Architectural,
Green roofs &
New development of 3D printer for houses.

4. CATEGORIES
Textile used in civil application are divided in two categories:
Buildtech
Geotextile
Buildtech:
Textile used in building houses & Construction called Buildtech or
Buildtech. Textile have increased usage indoor & outdoor for surface &
hidden applications. Textile traditional use in houses carpets & curtains,
but textile are also used in acoustic & thermal insulation, protection of
building against sun, wind, fire, water. Textile fibers are used with concrete
to enrich its properties & lowering the cost & protection against UV &
electromagnetic radiations. Textile integrated LED & other
electroluminescent material used for energy saving & use of more sunlight.

5. GEOTEXTILE
Geotextile is the combination of two words 'Geo' comes from the
Greek word meaning 'Earth' & textile. Geotextile defined as “Any
permeable textile material used for filtration, drainage,
separation, reinforcement and stabilization purposes as an
integral part of civil engineering structures of earth, rock or other
constructional materials”.

6. TYPES OF GEOTEXTILE
The geotextiles are further prepared in three
different categories:
Woven Fabrics:
Woven geotextile are manufactured weaving
technology as standard clothing textile.
Geosynthetics are of woven type, which can be
subdivided into categories based upon their method
of manufacture. this type has characteristic
appearance of two sets of parallel threads of yarn
that is warp and weft. Geotextile it is compose of two
sets of parallel yarns. Interlaced to form a planner
structure which include multifilament woven,
monofilament woven, slit film woven.

7.  NONWOVEN FABRIC
Nonwoven manufactured from either short staple fiber or continuous
filament yarn. The fiber can be bonded by thermal, chemical,
mechanical or mechanical techniques. Fibers are bonded together
into a planar structure, which include following:
Nonwoven mechanically needle punched
Nonwoven heat set.
Staple fiber and continuous filament fiber

8. KNITTED FABRIC
Interlocking a series of loops of yarn together. All of knitted
geo-synthetics are formed by using the knitting technique in
conjunction with some method of geo-synthetic manufacturer.
knitted geotextile are subset to woven geotextile and are found
as filters on pipes in two stage filter. multilayer geotextiles re
formed by bonding together nonwoven or woven geotextile.
They give high protection geotextile.
PET and PP are mostly used synthetic in civil engineering.

9. FIBER USED FOR GEOTEXTILE
Natural & man-made fibers both are used in geotextile
manufacturing.
Natural Fibers
Natural fibers that can be used in geotextile manufacture are
get from Jute, Sisal, Flax, Hemp, Ramie and Coir. Natural fibers
provided high modulus & strength and low breaking extension
& elasticity.

10. ADVANTAGES OF NATURAL FIBERS
Natural’s fibers are offered some of the mentioned below
advantages
Low cost
Strength/durability
Availability
Robustness
Good drape ability
Biodegradability/ environment friendly

11. SYNTHETIC FIBER
Synthetic fibers materials are also used for the manufacturing of
geotextiles. Main synthetics fiber used & their percentage of usages.
Polypropylene: 65%
Polyester: 30%
Polyamide: 1%
Polyethylene: 1%
Others: less than 1%

12. GEO TEXTILE FUNCTIONS
The mode of operation of geotextile in any application can be
defined by the following functions:

13. SEPARATOR FUNCTION
Geotextile as separator function, made a layer between fine
soil & course materials, separator provides high extension
together with excellent puncture resistance. Sustained flow
capacity and sand tightness without subsoil washout are
achieved at all strains.

14. APPLICATION OF GEOTEXTILE IN
SEPARATOR
Road construction for time saving, long lasting road life &
economical
Railway Ballast to protect against pumping phenomena
Geotextile placed between subgaurd & overlying layer
Sea and riverbed protection to protect soil, grow grass for
stabilization
Embankment Stabilization
Non permanent Roads

15. PICTURE

phenomenon mean water cannot rise
up
due to pressure

16. DRAIN FUNCTION
Geotextile in drainage function, - collects and redirects liquid
or gas. In civil engineering, the need for drainage has long
been predictable and has created the need for drainage filter to
prevent in-situ soil from being washed with water into the
drainage system.

17. APPLICATION OF GEOTEXTILE IN DRAINAGE
Filter around trench drain and edge drain to prevent soil from
migrating into aggregates.
Filters beneath pavement permeable bases, blanket drain and base
courses.
Drains for structure such as retaining wall and bridge abutment.
Tunnel lining system to protect the concrete
Geo-textile wraps for slotted or joined drain and well pipes.
Chimney and toe drains for earth dams and levees to provide
seepage control.

18. PICTURE

19. FILTER FUNCTION
Geotextile in filter function, structured that liquids can pass
through its thickness while it prevent the passage of soil
particles from the geotextile fabric. It has suitable level of
permeability and average pore size & pore size distribution
small to prevent soil migration.

20. APPLICATION OF GEOTEXTILE IN FILTER
Perforated pipe wrapped with geotextile to collect water
Filter between earth & gabions to protect structure at slope
Filter between permeable embankment
Filter preventing erosion

21. REINFORCEMENT FUNCTION
Geotextile in reinforcement function, stabilize the weak soil &
balance it by higher tensile strength of fabric. When the soil
properties are low we use geotextile to improve its properties.

22. APPLICATION OF GEOTEXTILE IN
REINFORCEMENT
Steep slide slop to reduce the angle & less space utilize
Reinforced wall & protect that wall with grass
Vertical faced walls
Reinforcement soil mattress to protect the subsoil pipes

23. CONTAINER FUNCTION
Geotextile container - holds or protects the materials such as
sand, rocks, fresh concrete.

24. APPLICATION OF GEOTEXTILE IN
CONTAINER
Framework fabric, geotextile filled with sand & stitched to
protect erosion
Basement protection of a bridge under water
Pile Protection with the aid of geotextile
Plugging of cavities
Sand fill tube
Different container application Sand fill tube for costal
protection

25. LIVING/GREEN ROOFS
Green Roofs or Living roofs are used in most of building &
attractiveness for better Environment. Living roofs have
features vegetation, growing media and waterproofing
membranes, water retention, drainage and irrigation systems.
Typical layer buildup for Living/Green Roofs

26. ADVANTAGES OF GREEN ROOFS
Living roofs increase the green area ratio on building sites and allow the
design of commercial and recreational roof gardens and terrace areas.
Reduced Maintenance – Green roofs geotextile materials protected against
UV radiations, snow & storm situations.
Water retention – Continuous supply of water to the root zone in the
absence of irrigation, rain water in retained & supply through capillary
action.
Superior Environment – By green roofs Planted area increased which reduce
greenhouse gases effect & plants absorbed pollutants.
Reduced Energy Costs – Living roofs provides insulation properties &
radiation is minimized which guarantee building is cooler in the summer
and warmer in winter.
Better Sound Protection – In the building noise transfer if reduced.
Drainage-Timely disposal of excess water not held within the engineering

27. NANO-TEXTILE IN CIVIL ENGINEERING
In buildtech and geotextiles, nanotechnology
play a vital role in a different way.
Nanotechnology improve existing textile
properties & offered additional functional
performance by increasing chemical,
mechanical, biological & photochemical
properties. Nanotechnology also make
possible arrangement of different functions in
the same textile or establish completely new
properties.

28. APPLICATION OF NANOTECHNOLOGY IN
BUILDING
Self-healing concrete,
Localized crack repair,
Reinforcement of critical walls,
Wrapping of existing columns,
Protection against earthquake or hurricanes,
Explosive incidents and protection purposes.

29. ACOUSTIC & THERMAL INSULATION
TEXTILE
Geotextile materials used in house roof for thermal insulation.
Fabric are also made which protect the building from sun light.
One of the example is Mermet solar protection fabrics are
designed for external and internal blinds. In below figure an
example of intelligent textile fabric which adopt according to
thermal permeability to costume temperature, have possibility
to reduce cost of heating or air conditioning.

30. ARCHITECTURAL TEXTILE
In architecture, textile materials proposed
very fascinating degree of independence with
respect to their properties. Present day
architectures are creating room for textiles in
building constructions & revived the principle
of the tent as an architectural form and do
advancement in this concept further – not only
in temporary structures but also in permanent
buildings. Technical and durable fabrics
permit their consumption into a highly

31. 3-D PRINTER FOR HOUSE BUILDING
3D printing technology we are make to made
things in a new way. Main advantages of this
technology is build houses with
Cost Saving
Environmental friendly
Time saving & very fast way An Italian company
World’s Advanced Saving Project (WASP) showed
world’s largest 3D printer, Big Delta, which can
create budget-friendly mud huts in one
continuous printing session.

32. CONCLUSION
"Textiles instead of concrete" is not only a slogan, but a fact".
This report describes various textile in buildtech & civil
engineering application has shown where, why and how this
area is interesting and important by analyzing the textile
structure. The benefits of using textile material in civil
engineering are the potentials of textile fibers to create a lot of
applications, which are profitable in products for durability,
