Lowering the Carbon Footprint is one of the strongest advantages by using HDPE geomembrane instead of traditional way for waterproofing as compacted clays.
A HDPE liner 1.5 mm could give similar watertight as 0,60 m compacted of high quality and homogeneous clay with lower permeability than 1 x 10-11 m/sec (ASTM D 5887). Based on several scientist survey, considering all resources and energy to become either products as a waterproofing barrier, the geosynthetics (geomembrane HDPE 1.5 mm) takes up lower carbon dioxide equivalent, therefore it is more environmentally friendly solution.
