MONOLITHIC ROOF-PROTECTIVE COATING OF OPERATIONAL PURPOSE Russian patent published in 2012 - IPC E04D11/02 

FIELD: construction.

SUBSTANCE: in a monolithic roof - a protective coating of operational purpose made as multilayer and consisting of a slope-forming screed 2, laid on a base 1 of a power floor slab, a priming layer 3, filled with quartz sand 4 during application, which serves function of a steam insulation layer, a hydraulic insulation layer 5 is made as a hydraulic insulation membrane by pouring polymer materials of higher elasticity, for instance, methyl methacrylate, types of matacryl, polyurethane and other polymers that withstand tension (elongation) in case of rupture of at least 200%. The bearing high-strength layer 6 is made of a polymer binder of similar origin, but with lower deformation characteristics and is filled with quartz sand by at least 100% of the binder's mass. In the finishing top layer 7, made as polymer, thickness, colour, chemical resistance, extent of roughness and other characteristics are determined by conditions of operations of a specific roof. At the same time all polymer layer are made in a seamless monolithic version.

EFFECT: increased operational reliability of the roof.
