Nonwoven geotextile is needle-punched and made of short polyester or polypropylene fiber ; it is a kind of permeable geosynthetics and functions as filtration, drainage, seperatoin, reinforcement and etc.
1.Good Flexibility: flexible in structures preventing block drainage holes.
2.Resistant to corrosion, acids and alkalis, anti-age;
3.Good performance in filtration under high pressure of soil.
4. Environment friendly and easy construction
1. 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.
2.Separation: to separate two layers of soil with different physical properties, such as the separation of road
gravel from soft sub-base materials.
3.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.
4.Reinforcement: to improve the load bearing capacity of a specific soil structure, such as the reinforcement of retaininng wall.
