Abstract
The invention relates to a process for sealing an above-ground or underground construction. In particular it involves the use of non-reactive hot melt adhesives and flexible polyolefin films. This procedure in particular has the advantages that good and long-lasting adhesion can be achieved very quickly, and that in particular by using polyolefin strips coated with non-reactive hot melt adhesives, insulating strips can be obtained simply which are non-tacky at room temperature and can be processed and bonded easily at the construction site.
Claims3
A method for sealing an underground or above-ground construction comprising the step of applying a non-reactive hot melt adhesive coated flexible polyolefin sealing film, which is non-tacky at 25° C.
A composite, which has a
- i) layer of a polyolefin sealing film,
- ii) layer of a hot melt adhesive compound, and
- iii) an underground or above-ground construction,
- wherein the layer of the hot melt adhesive compound is disposed between the layer of the polyolefin sealing film and the underground or above-ground construction.
