Products from the Geosynthetics range, Geotextiles are composed from synthetic polypropylene/polyester fibres through a mechanical process of needling the fabric and adding, when necessary, a thermo fused process, resulting in a uniform porous structure with excellent tensile strength and chemical deterioration.

Geotextiles are available in rolls of various sizes and three widely accepted colours – white, black and grey and can therefore, be customised as per the customer’s requirements.

Functions of Geotextiles:

• Filtration
• Separation
• Reinforcement
• Protection
• Drainage
• Waterproofing

Advantages of Geotextiles:

• A cheaper, cost-effective and quicker alter native to the traditional construction methods
• Versatile, flexible, resistant and adaptable to uneven terrain
• High puncture resistance
• Excellent filter characteristics at all strains
• Increases the life of facilities
• Specially chosen fibres for high UV protection

Types:

• Woven Geotextiles are manufactured by polypropylene (PP) film and polyester yarns. Woven Geotextiles are often used for soil reinforcement, separation and stabilization. The high tensile strength and low elongation properties of woven Geo- textiles impart stability into the road section reducing rutting and extending the lifespan of the road. Woven Geotextiles are also used in filtering and reinforcement
• Non-woven Geotextile are manufactured by polypropylene (PP) and polyester Geotextiles are made from a needle punched polypropylene staple fibre. These fibres are cut, opened, laid on to a web, needled, inspected, tested and finally rolled to form a Geotextile. Nonwoven Geotextiles are multipurpose fabrics that are felt-like in appearance. They have a wide range of applications in civil environmental engineering and construction projects.
• Nonwoven drainage fabrics are an economical alternative to graded aggregate and sand filters and can eliminate many of the problems associated with using, purchasing and transporting aggregate.
• Application areas of Geotextiles:
•  Municipal and hazardous waste landfills, effluent treatment plants

Geotextile products have been designed and adapted especially for landfill applications. They are characterized by high puncture resistance at minimum cost; widths for minimum overlap and cylinder test information for every basal liner application.

• Roads

Geotextiles can be used for separation, filtration and stabilization of road construction works.

Woven Geotextile and non-woven Geotextiles provide long term separation of the aggregate base from the sub grade soil. By separating these two materials, the Geotextile maintains the original thickness of the roadway aggregate. This is the most important Geotextile function for roads, particularly where the road is being constructed on weak sub-grade soils.

Higher strength PP and polyester woven Geotextiles provide the much necessary strength to the roads. Geotextiles allow ground water to pass into the subsurface drain without eroding the soil, making the life of the roads very long.

• Railways

The use of high strength woven Geotextiles during the construction of Railway tracks increases the periods between track maintenance. Geotextiles are usually placed  between the existing formation and the ballast layer to prevent the sub- grade from pumping in to the ballast layer, thereby maintaining structural integrity.

Non-woven Geotextiles are useful for separation, performing well under such diverse applications as paver walkways or railroad track.

•  Tunnels

Geotextiles are used in tunnel construction for the protection   of the sealing membrane. Geoconstech products fulfil all the technical requirements for scaling up to modern tunnel construction work.

• Stadiums, Hill Resorts and Golf Courses

In most leisure destinations such as stadiums, resorts or golf courses; Geotextiles have been actively used as a separating fabric to stop the migration of sub-soil fines at the bunker base from passing through to the clean soil. They are also used as   a wrapping for subsoil drainage.

• Concrete basement and roof water proofing liners

Coatings and membranes applied to concrete structures are often in the need of protection. Non-woven Geotextile can be used as a barrier and insulation in the water proofing of Dams, Canals, Basements, Malls, Gardens, Terraces, storage ponds, car parks and many more. Thick, non-woven Geotextiles are the easily applied and proven solution.
