Type A external (positive side) waterproofing DualProof is a fully and permanently bonded, self-adhesive, composite sheet which does not only waterproof but protects against gas and chemicals. It consists of a sealed two layer highly flexible PVC membrane laminated with a non-woven PP-fleece. The PVC and fleece are manufactured together as one unit due to a highly advanced process. The fleece is water resistant and easy to clean. It's a pre-applied membrane joined at overlaps with CEM 805 adeshive and is installed without heat or open-flame. It is applied before the Steel reinforcement is fixed and the concrete poured, the fleece integrates into the concrete eliminating the risk of blisters or water tracking between layers.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Delta Membrane Systems Limited is consulted before specifying.
