Waterproof membrane with good adhesion to concrete
The invention relates to a waterproof membrane comprising a barrier layer and a functional layer. The functional layer contains a thermoplastic polymer, which changes consistency under the influence of highly alkaline media, and an adhesive. The invention also relates to the production and to the use of said membrane. The functional layer, which can be designed in the form of a film, a coating, or a nonwoven fabric, the fibers in the fabric consisting of a hard core that is surrounded by a polymer layer, is inert prior to coming into contact with liquid concrete and acts as a protective layer. Thus, the membrane is protected from premature aging and allows work to be performed with the seal in place. During the concreting process, i.e. when the functional layer comes into contact with liquid concrete, the polymer dissolves and thus allows the adhesive to bond to the concrete. The functional layer thus acts as an adhesive sealing compound and the seal is leakproof.
