Geotextile is a water-permeable geosynthetic material made of synthetic fibers by needling or weaving. Geotextile is one new material of geosynthetics. The finished product is cloth-like, with a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and nonwoven geotextiles (filament geotextiles, short-filament geotextiles, filament woven geotextile, and PP woven geotextile).
Geotextiles are with excellent filtering, drainage, isolation, reinforcement and protection. Characterized by lightweight, high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance and corrosion resistance.
