The disclosed thermally bondable adhesive tape backing has a pressure-sensitive adhesive at a surface and a thermoplastic polyurethane adhesive at an opposite surface for thermal bonding to a device. The thermoplastic polyurethane adhesive softens and melts at a relatively low temperature. Therefore, melting of thermoplastic polyurethane adhesive is achieved while the pressure-sensitive adhesive remains in place and is not pressed away at the region of the thermal bonding.

The adhesive tape includes: a resin layer that is formed by applying resin coating, the resin coating containing a resin having an acid number of 50 mg/g or more and 130 mg/g or less, and at least one type of cross-linking agent selected from between an epoxy-based cross-linking agent and a metal chelate cross-linking agent; and an adhesive layer that is laminated on or above the resin layer, and is formed by applying adhesive coating, the adhesive coating containing a resin including a hydroxyl group, and a metal chelate compound.

A waterproof membrane is described that includes a barrier layer and a functional layer. The functional layer can include a thermoplastic polymer that changes consistency under the influence of highly alkaline media, and an adhesive. The production and use of the membrane are also described. The functional layer of the membrane can be designed in the form of a film, a coating, or a nonwoven fabric. The fibers in the fabric can include 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.
