Description

Continuous polyester filament non woven geotextile is the needle-punched product which can offer excellent water flow properties for drainage and other applications.

Application

Filtration: when water passes from a fine-grained to coarse grained layer, non-woven geotextile can retain fine particles well, such as water can flow 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 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 a retaining wall.
