Single and double texture surface high-density polyethylene (HDPE) geomembrane is produced from high-grade high-density polyethylene resin by invention patent technology of the company. Besides performances of flat surface high density, the also has higher ultraviolet radiation resistance, improves friction factor, and increases side slope stability of earthwork composite material so as to make available bearing volume of earthwork film to be maximum, to suit design need of side slope and vertical projects better and to improve project stability. It is mainly used in landfill yard and mine.
