FIELD: construction.SUBSTANCE: invention relates to sealing of surface or underground structure. Method for sealing of underground or ground structure, involving coating flexible polyolefin sealing film non-reactive hot-melt adhesive composition to produce polyolefin sealing film coated with hot-melt adhesive, which is non-adhesive at temperature of 25 °C, placing of produced film on ground surface or underground structure, heat supply for partial melting of said composition, cooling of adhesive composition with formation of adhesive joint between said film and surface structure, where said adhesive composition does not contain above polymers that may lead to formation of more high-molecular compounds. Use of flexible polyolefin sealing film, obtained using said method, to seal underground or ground structure. Composite material obtained using described method.EFFECT: technical result is improvement of sealing reliability.13 cl, 5 dwg, 1 tbl |
