Gas Resistant Self Adhesive Membrane is generally used within foundation construction, predominantly to prevent the transmission of ground gases in both horizontal and vertical applications. It is manufactured using an aluminium/polythene laminate coated on one surface, with an additional layer of self-adhesive polymer modified bitumen.
The use of the Gas Resistant Self Adhesive Membrane is suggested where combined gas protection and damp proofing is required. The membrane can be installed both horizontally and vertically onto suitably primed substrates including concrete, masonry and steel.
Suitable for use in conjunction with Tri-gas Membrane, Radon Membrane and Gas Resistant DPC for the protection against the ingress of methane, carbon dioxide, radon and damp.
All surfaces that the membrane is applied to should be primed using the Puraflex Primer prior to installation.

Note: All membrane types also provide damp proofing protection, however should there be the additional risk posed by hydrostatic water pressure, please contact a member of the Cordek Technical Team for additional advice.
