Non-woven Geotextile
Overview
Non-woven geotextile is needle-punched and made of polypropylene fiber ; it is a kind of permeable geosynthetics and functions as filtration, drainage, separation, reinforcement and etc.
Performance
a.Good Flexibility, flexible in structures preventing drainage holes from blocking.
b.Anti-corrosion, acids alkalis, anti-age.
c.Good performance in filtration under high pressure of soil.
d. Environment friendly and easy laying.
Application
a Filtration: when water passes from a fine-grained to coarse grained layer, Non-woven Geo-textiles can retain fine particles well. Such as when water flows from a sandy soil into a Geo-textile wrapped gravel drain.
b Separation: to separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.
c 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.
d Reinforcement: to improve the load bearing capacity of a specific soil structure, such as the reinforcement of retaining wall.
