Generally speaking, geotextiles are made of high-quality polymer materials, including polypropylene(PP), polyester(PET), polyethylene, or polyamides which are handled by woven skills, needle-punched skills, or some heating methods. Geotextiles are durable geosynthetic materials that can be widely applied in the separation, filtration, reinforcement, protection, retainage, and drainage of the soil. Geotextiles are marvelous materials for civil constructing projects such as the anti-seepage engineering of bridges, harbors, reservoirs, canals, dams, and any other retainage project. The 4 types of geotextiles we produce are divided into Polyester(PET) Filament Nonwoven Geotextiles, Polyester(PET) Staple Fiber Needle Punched Nonwoven Geotextiles, Polypropylene(PP) Staple Fiber Needle Punched Nonwoven Geotextiles, and Polypropylene(PP) Woven Geotextiles.
