TRST HDPE Textured Geomembrane is a new type of anti-leakage product, its one side textured and both sides textured can increase its coefficient of friction and function of preventing leakage, especially used in anti-leakage in slope and vertical surface which required enhanced stability.
Mainly used in landfills, wastewater treatment plants, reservoirs, dams, channels, water pools, roads, tunnels, airports, underground projects, submarine projects, anti-seepage liner of desert farmland-building.
