The surface of the textured geo membrane has rough stone patterns, which is a new type of anti -seepage material. It is made of high -density polyethylene, low -density polyethylene and other materials. There are two kinds of textured geofilm: single-rough and double -rough surfaces. The membrane can increase the friction coefficient, which can play a role in enhancing the adhesion between the foundation and the soil. It has a non -slip function.  So rough geomembrane are more applied to steep slopes and vertical anti -seepage, which can improve engineering stability.
