GEOTEXTILE FABRIC (NON-WOVEN) MEMBRANE 140gsm

GEOTEXTILE (NON WOVEN) FABRIC (DRAINAGE & SEPARATION)

GEOTEXTILE

Non-woven geotextiles are made in two different ways: either using staple fibre - short fibres interlocked together, usually through a needling process; or continuous filament - long, continuous strands of synthetic threads which are laid together and then needled to improve strength.

Non-woven geotextiles are usually used for separation, drainage, filtration and protection applications whilst woven geotextiles are typically used for reinforcement applications. 

GEOTEXTILE APPLICATIONS

Separation

Engineers and contractors typically use non-woven geotextiles in the construction of roads, railways and embankments where the ground is soft and unstable. Using a layer of Geotextile to separate the soft ground from the fill material will reduce the amount of fill required, increase the life span of the road or rail structure and cut long-term maintenance costs.

Drainage

The permeability of non-woven geotextiles means that they can provide excellent drainage properties when used as part of subsoil drainage systems. Typically lighter, or thinner, grades of geotextiles ar used in drainage applications as they offer better drainage properties than heaver, or thicker, geotextiles.

Filtration

Nonwoven geotextiles are highly porous, allowing water to pass through while preventing soil migration. When used in revetment and subsoil drainage projects, geotextiles are more cost effective than natural filters such as sand or aggregate. As with drainage applications, lighter grades of geotextile offer greater filtration properties.

Protection of Geomembranes

Using heavyweight nonwoven 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, minimising the chances of leakage in the long term.
