Visqueen Radon Membrane can be used in most common floor constructions. It is installed in a similar way to damp proof membranes, but with a much greater attention to workmanship and detailing in order to achieve effective sealing at all locations. Visqueen Radon Membrane is not intended for use where there is the risk of hydrostatic pressure. The product should be installed on a blinded or smooth surface allowing adequate overlap for jointing between the sheets and avoiding bridging (i.e. areas of unsupported membrane). In order to provide a continuous barrier the membrane must be joined to the Visqueen Zedex CPT High Performance DPC.
