BBA Agrément Certificate
Low density polyethylene damp proof membrane.
BBA 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. It is produced from 100% recycled material. 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.
