Abstract
During the winter, many tons of deicing salts are spread on roads. These salts produce large quantities of concentrated chloride solution, which cars bring into parking garages. Some of this solution percolates through the concrete deck, entering fine cracks in the surface and promoting corrosion of reinforcing steel. Waterproofing membranes applied to decks can help prevent moisture and salt ingress and subsequent rebar corrosion.Elastomeric waterproofing membranes in temperate climates are "subject to rigorous temperature extremes, exposure to damaging chemicals, and high wear. A membrane's ability to withstand these harsh conditions depends on critical characteristics tied to the physical and chemical properties inherent in the polymer resin from which the membrane is made. Properties such as abrasion resistance are provided by layered, composite membrane systems.
