Geotextile is a permeable geosynthetic material made of synthetic fibers being needle-punched and woven. It’s cloth-shaped, and the width is 4-6m, the length is 50-100m. Geotextile is divided into Woven Geotextile and Nonwoven Geotextile. Geotextile has advantages of filtration, drainage, isolation, enforcement, anti-leakage and protection. Geotextile has the advantages of light weight, high tensile strength, good permeability, high temperature resistance, anti-freezing, aging resistance and corrosion resistance.  Geotextile is one kind of geosynthetics. Geosynthetics application originated in the 1950s, and domestic geotextiles is part of national 8th Five-Year Plan. China promulgated the Geosynthetics, Short-fiber Needle Punched Nonwoven Geotextiles Standard in 1998 (GB/T17638-1998), and  the geotextile has been widely applied in many fields at present.
