FIELD: construction.
SUBSTANCE: invention relates to hydraulic and civil construction and can be used for the building structures, hydraulic structures from low-temperature soils and rocks waterproofing, as well as in construction and repair of roads. Described is a waterproofing composition, comprising the following components, wt%: polyvinyl alcohol 5–7, oxyethylated alkylphenol – neonol AF9-12 0.05–0.08, oxidized polymeric petroleum resin C9 10–30, water – the balance. During the freezing-defrosting process, the composition forms filled cryogel.
EFFECT: improved structural and mechanical properties, high hydrophobicity, ability to maintain its physical and mechanical properties for a long time with temperature differences from -40 °C to +65 °C in the humid environment.
