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. For typical plumbing and drainage applications we recommend use of our Filterwrap geotextile.

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. We would recommend use of bidim A14 or A19 for most filtration applications. 

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. Needle free bidim geotextiles are commonly specified in landfill and containment applications to prevent damage to the underlying liner. 

Reinforcement
Woven geotextiles are used in reinforcement applications, such as the construction of embankments on soft soils. Woven geotextiles provide reinforcement by maintaining the stability of soil by carrying tensile loads.
