A range of coating products have been developed offering protection for both new and existing concrete structures. Correctly formulated surface coatings provide an effective barrier to corrosion/erosion attack, forming an impermeable layer over the surface of the concrete to prevent deterioration which can occur to the surface as a result of various factors, such as, carbonation, sulphation, re-bar attack, impact, erosion and cracking. Applications on concrete substrates can be made on flooring, concrete pipework, chemical bunds, tanks, neutralization pits, masonry and other specialist constructions.
