HDPE Textured Geomembrane

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.

Application

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.
