Rough surface geomembrane is a type of geomembrane, which can be widely used in various slope seepage projects due to its rough surface providing high friction. Currently, there are mainly three types of rough surface geomembranes in China: single rough surface geomembrane, double rough surface geomembrane, and column point geomembrane.

   Rough-textured geomembrane boasts excellent temperature adaptability, weldability, weather resistance, and good aging resistance, chemical corrosion resistance, environmental stress cracking resistance, and puncture resistance. Primarily used for slope seepage prevention, the rough-textured geomembrane is chosen to enhance the friction between the geomembrane and the slope surface, preventing slippage and improving engineering stability.
