FIELD: construction.
SUBSTANCE: concerns rolled waterproofing material and a method for its use for waterproofing vertical underground structures in pits with vertical fencing. Rolled waterproofing material contains a waterproofing layer of fabric made of a polyester base with a polymer-bitumen binder applied to it and located on opposite sides of the waterproofing layer, a lower polymer protective layer and an upper adhesive layer, where the upper adhesive layer is intended for contact with the concrete surface and is made of granules from igneous rocks coated with a coating composition of acrylic latex containing a component that acts as an adhesion promoter to both bitumen and concrete.
EFFECT: significant increase in the reliability of waterproofing protection of underground and buried buildings and structures during their construction in dense urban areas.
