USE OF COATED DISPERSION ADHESIVE LAYER OF POLYVINYL CHLORIDE SEALING FILMS FOR MAKING TIGHT COATING Russian patent published in 2016 - IPC E04D5/14 E04B1/66 B32B27/08 B32B27/32 

FIELD: construction.

SUBSTANCE: present invention relates to method of sealing of surface or underground structure. Sealing method of underground or ground structure, which includes: a) application of inert dispersion adhesive substance on elastic sealing polyvinyl chloride film, b) curing adhesive substance on open air during formation of polyvinyl chloride sealing film-coated dried adhesive substance and non-sticky at room temperature, b) placing of obtained coated film on surface of underground or ground structure, as a result, dried adhesive substance is arranged between said film and surface, d) heat supply with melting or partial melting of bonding agent, e) cooling of bonding agent during formation of adhesive joint between said film and surface structure, wherein said adhesive does not contain isocyanate, alkoxysilate, epoxy or (meth) acrylate groups and polymers which chemically react with each other at room temperature or melting temperature with formation of high-molecular compounds. Use of said polyvinyl chloride sealing film for sealing of underground or ground structure. Composite object obtained using described method, having: i) layer of polyvinyl chloride sealing film, ii) layer of dried inert dispersion adhesive substance, iii) underground or ground structure. Invention is developed in dependent claims.

EFFECT: technical result is improvement of sealing reliability.
