Visqueen Self Adhesive Membrane (SAM) is a two ply self adhesive waterproofing system. The high density is tough to provide resistance to punctures and tearing. It can be used as a damp proof membrane or a tanking membrane – for above and below ground and for both horizontal and vertical applications. The membrane protects from the ingress of water and associated water-borne alkalis present in some mortar and concrete. Use with Visqueen High Performance Tanking Primer to obtain optimum adhesion.
