Coatings for bridges, tunnels and other industrial structures
For bridges and tunnels surfaces, polymeric coatings are widely used. Standard polymeric coating of bridge includes waterproofing elements, components providing anticorrosive protection of steel and reinforced-concrete structures and etc. A common for coatings used in tunnels is the application of special compound capable to bind chemically the moisture contained in buried concrete surfaces, which polymerization results in formation of strong waterproofing film membrane.
Special compositions of elastomer polyurea compounds are also used to provide external waterproof for the part of structure which surface is in continuous water contact. Besides, there are technical solutions allowing to apply polyurea coatings for temporary strengthening of stripping area before tunnel crown reinforcement and etc.
A big variety of formulas used in systemic polyurea elastomer enables to use them as coatings, facing compositions and protective membranes for bridges (as anticorrosive coating for trussed metal structures and waterproofing layer for roadway under bridge superstructures), tunnels, high-speed railway lines, motor roads and other transportation facilities.
