Patent ID: 8778131

Claim:
A process for sealing an underground or above-ground structure, comprising: a) applying a non-reactive dispersion adhesive compound to a flexible polyvinyl chloride sealing film; b) exposing the non-reactive dispersion adhesive compound to air while forming a polyvinyl chloride sealing film coated with a dispersion adhesive compound which is non-tacky at room temperature; c) laying the polyvinyl chloride sealing film coated with dispersion adhesive compound onto the surface of an underground or above-ground structure, so that as a result the dispersion adhesive compound is disposed between the polyvinyl chloride sealing film and the surface; d) introduction of heat with fusion or partial melting of the dispersion adhesive compound; and e) cooling of the dispersion adhesive compound, forming an adhesive bond between the flexible polyvinyl chloride sealing film and the surface of the structure.
