There are three main series of geotextiles:
1. Needle-punched non-woven geotextile, the specification is between 100g/m2-600g/m2. The main raw material is polyester staple fiber or polypropylene staple fiber, which is made by needle punching. The main uses are: rivers, seas, lakes and rivers. Embankment slope protection, sea reclamation, wharf, ship lock flood control and other projects are effective ways to conserve water and soil and prevent piping through back filtration.
2. Needle-punched non-woven fabric and PE membrane composite geotextile, the specification is one cloth and one membrane, two cloth and one membrane, the maximum width is 4.2 meters. The main raw material is needle-punched non-woven fabric with polyester staple fiber, and PE membrane is made by compounding. , The main purpose is to prevent seepage, suitable for railways, highways, tunnels, subways, airports and other projects.
3. Non-woven and woven composite geotextiles, including non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, suitable for foundation reinforcement and adjustment of permeability coefficient of infrastructure engineering facilities.
