PIFA Approved Damp Proof Membrane

Description

PIFA approved low density polyethylene membrane, for use in solid concrete ground floors not subject to hydrostatic pressure, to protect buildings against moisture from the ground. The membranes and the methods of jointing provide an effective barrier to the passage of liquid water and water vapour from the ground and have a high resistance to puncture. On smooth or blinded surfaces they will not be damaged by foot or site traffic, e.g. wheelbarrows. Exposure to ultraviolet light, including sunlight will embrittle the membrane and is therefore not recommended for uses where it is exposed to long periods of outdoor weathering. Offers high chemical resistance.
