HDPE Liners are impermeable, high-quality barriers manufactured from high-density polyethylene (HDPE). The membrane has a high chemical resistance and is ideal for use on sites affected by hydrocarbon and VOC contamination. They are also resistant to stress cracking which make them a particularly robust liner. They tend to be used in the containment and management of solids, liquids and gases and will also effectively prevent the ingress of a number of other harmful gases, including radon, as well other toxic industrial contaminants.
