FIELD: hydraulic engineering and civil engineering.
SUBSTANCE: invention relates to the field of hydraulic engineering and civil engineering. Proposed waterproofing composition containing polyvinyl alcohol (5-10 wt.%), polyfluorinated alcohol as a filler - 1,1,5-trihydrooctafluoroamyl alcohol or 1,1,7-trihydrododecafluoroheithyl alcohol (10-50 wt.%), alkylarylsulfonate DS PAC (0.05-0.1 wt.%) and water (the rest), which after freezing-thawing is a filled cryogel.
EFFECT: creation of a waterproofing composition that has high hydrophobicity and elasticity, as well as the ability to maintain its physical and mechanical characteristics for a long time with significant temperature changes in a humid environment.
