ABSTRACT
Lowering the Carbon Footprint is one of the most important reasons for using HDPE geomembrane instead of traditional ways of waterproofing such as compacted clay. An HDPE liner in 1.5 mm thickness could give similar watertight properties as using 0.60 m of high quality and homogeneous compacted clay with lower permeability than 1 × 10-11 m/sec (ASTM D 5887). Based on several scientific surveys, and when considering all resources and energy needed to install both products as a waterproofing barrier, the geosynthetic option (HDPE Geomembrane 1.5 mm) means a lower carbon dioxide equivalent, therefore it is a more environmentally friendly solution.
