Self adhesive membrane designed for adhesion to suitably primed substrates. Generally used to provide combined damp proofing, VOC and gas protection to foundation constructions.
Generally used within foundation construction, predominantly to prevent the transmission of VOCs and ground gases in both horizontal and vertical applications.
A high performance hydrocarbon and chemical resistant barrier with resistance to a wide range of pollutants including hydrocarbons, industrial chemicals, toxic waste, natural and radioactive gases. It comprises of aprotective polymeric layer and adhesive bitumen layer, either side of a chemical resistant inner core.
