Visqueen High Performance Radon Membrane is an LDPE un-reinforced membrane. Visqueen High Performance Radon Membrane™ is suitable for use in concrete floors not subject to hydrostatic pressure. The product can be installed as an over-site membrane, either between a Sand blinded hardcore (50mm of sand minimum) bed and the base concrete, or layered on top of high-density insulation (25kg/m3) with a concrete screed layered over it.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Visqueen Building Products is consulted before specifying.
