PIFA Approved Damp Proof Membrane
QA Certificate
Certificate type
Low density polyethylene damp proof membrane.
Application
For use in solid concrete ground floors not subject to hydrostatic pressure, to protect buildings against moisture from the ground.
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.
Performance:
- Tear strength: 40 N/mm.
- Tensile strength: 14.4 mPa
- Water vapour transmission rate (to BS 3177): 1.0 g/m²/day (250 µm), 0.8 g/m²/day (300 µm), 0.5 g/m²/day (500 µm).
