Abstract
The protection that parking garage membrane systems provide is contingent upon how well and for how long they function in service. They should not show any detrimental aging effects, such as an increase in brittleness, and should be unaffected by exposure to freeze-thaw cycles, salt spray, and the variety of chemicals found in service. Durability of such membranes is dependent on the interaction of the material with the various factors involved in the parking garage environment. Therefore, it is important to understand the impact of the various environmental conditions as well as the properties and limitations of the materials so that degradation problems can he avoided. Also, an understanding of the mechanism of degradation is required to improve and predict membrane durability. Typical defects that result from the deterioration of membranes include chalking, peeling, blistering, alligatoring, checking and wrinkling.' The cause may be due to premature solvent evaporation, improper surface preparation, chemical attack by aggressive liquids and atmospheric pollutants, heat and light aging, membrane incompatibility, or moisture problems.
