GEOTEXTILE (NON WOVEN) FABRIC (DRAINAGE & SEPARATION)

Non-woven geotextiles are manufactured in two distinct ways: either by using staple fibre, which involves short fibres interlocked together typically through a needling process, or by using continuous filament, which consists of long, continuous strands of synthetic threads laid together and then needled to enhance strength. These geotextiles are predominantly employed for separation, drainage, filtration, and protection applications, whereas woven geotextiles are generally used for reinforcement purposes.

GEOTEXTILE APPLICATIONS

SeparationEngineers and contractors frequently utilize non-woven geotextiles in the construction of roads, railways, and embankments where the ground is soft and unstable. By incorporating a layer of geotextile to separate the soft ground from the fill material, the amount of fill required is reduced, the lifespan of the road or rail structure is extended, and long-term maintenance costs are minimized.

DrainageThe permeability of non-woven geotextiles allows them to provide excellent drainage properties when integrated into subsoil drainage systems. Typically, lighter or thinner grades of geotextiles are used in drainage applications as they offer superior drainage properties compared to heavier or thicker geotextiles.

FiltrationNon-woven geotextiles are highly porous, enabling water to pass through while preventing soil migration. When employed in revetment and subsoil drainage projects, geotextiles prove to be more cost-effective than natural filters such as sand or aggregate. As with drainage applications, lighter grades of geotextile offer enhanced filtration properties.

Protection of GeomembranesUsing heavyweight non-woven geotextiles in landfills, ponds, tailings dams, or any other containment facility extends the life of the lining system by protecting it from punctures and excessive deformation. The geotextile acts as a cushioning and stress-relieving layer, significantly reducing the chances of long-term leakage.
