The use of protective coatings is to enhance the durability of concrete structures by creating a barrier that will limit the penetration of water, acids, chemicals, solvents, and chlorides that will breakdown industrial or municipal infrastructure. Corrosion in concrete is not just caused by the constituents of wastewater, it can also be caused by the cleaning procedures of water treatment or membrane bioreactor (MBR) systems. Lining solution technologies presented included systems comprised of 100% solids epoxies, epoxy laminate alternatives and elastomer polyurethane applications.

The purpose of this paper is to provide an understanding of two lining solutions: elastomer polyurethane and epoxy laminate systems. The paper will provide insight into the effects of corrosion on concrete infrastructures, identify the various lining solutions, compare, and contrast the application techniques, cost structure, product performance in these environments and highlight project impacts of these solutions that should be considered by specifiers and clients when selecting the lining system for their projects.
