[vc_row][vc_column][vc_empty_space height=”50px”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]A waterproofing membrane made of high-density polyethylene (HDPE) or low-density polyethylene (LLDPE) with an additional antioxidant additive package which extends its design life.<\/p>\n

This additional stabilisation means the geomembrane can be used in projects with more abrasive chemical products or more extreme service conditions. The additional antioxidants are more resistant in this type of environment, and are retained inside the polymer matrix. Consequently, the mechanical properties of the Alvatech HP-OIT geomembrane will not deteriorate over time.
