Self adhesive membrane designed for adhesion to suitably primed substrates. Generally used to provide combined damp proofing and gas protection to foundation constructions.
Used within foundation construction, predominantly to prevent the transmission of ground gases in both horizontal and vertical applications. Can be installed in both vertical and horizontal applications, above and below ground.
Self-adhesive membrane which is manufactured using an aluminium/ polythene laminate coated on one surface, with an additional layer of self-adhesive polymer modified bitumen.
