Application:
■ Filtration: when water passes from a fine-grained to a coarse grained layer, Non-woven Geotextiles can retain fine particles
well. Such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.
■ Separation: to separate two layers of soil with different physical properties, such as the separation of road
gravel from soft sub-base materials.
■ Drainage: to drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil,
such as the gas vent layer in a landfill cap.
■ Reinforcement: to improve the load bearing capacity of a specific soil structure, such as the reinforcement of retaining wall.
