WJG-980 series of polymer self-adhesive waterproof membrane
WJG-980 polymer self-adhesive waterproof membrane is a new generation of waterproof membrane developed using advanced domestic and international technologies that can firmly bond with post-cast concrete structures. It uses a specially formulated, high-performance polymer membrane as the main waterproof layer. The surface of the main waterproof layer is covered with a pressure-sensitive polymer self-adhesive (butyl rubber), an environmental protection layer, or a release film (paper). A 70mm wide self-adhesive lap joint is provided on one long side of the roll (when covered with an environmental protection layer). After the pressure-sensitive polymer self-adhesive (butyl rubber), through the environmental protection layer, reacts and solidifies with the liquid concrete, a seamless bond is formed between the waterproof layer and the concrete structure, eliminating the risk of water leakage and effectively improving the waterproof effect of the system.
