WATERPROOFING OF REINFORCED CONCRETE COMPONENTS IN ENGINEERING STRUCTURES Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this can be used in repair of engineering structures such as bridges. Waterproofing of reinforced concrete components is made up of external coating, protective layer made of asphalt or concrete, polymeric waterproofing layer which is made in the form of laminated rolled material. Rolled material incorporates two polymeric layers made of rubber on base of combined chlorine-sulfureted polyethylene and synthetic butadiene rubber taken in ratio of 85-95% : 5-15% respectively. Located between these two layers is layer of glass cloth. Aforesaid laminated rolled material is attached to reinforced concrete structure being protected by means of cementing mastic which is based on chlorine-sulfureted polyethylene. Aforesaid arrangement of waterproofing for reinforced concrete components of engineering structures possesses high performance characteristics due to its high frost-resistance and superb cohesion of polymeric waterproofing layer to reinforced concrete structure being protected. EFFECT: higher efficiency. 1 tbl, 1 dwg
