AbstractThe slab of a parking garage serves as a structural diaphragm and wearing surface. It also must provide protection for the space below. Those functions require a deck to be impervious to liquids and stop water from seeping through cracks. Depending on the type of structure, North American Standards require, as a minimum, sealing the top surface of the deck with penetrating sealers or elastomeric traffic bearing membranes, with or without epoxy coated reinforcing steel. Elastomeric membranes are widely usedto prevent the ingress of water and chloride ions, both for new and existing structures. The durability of membranes is affected by a number of factors, including poor installation, variation in product uniformity, and exposure to, adverse in-service conditions. A study of six proprietary membranes showed many degradative agents encountered in the parking garage environment affected critical properties, seriously reducing short- and long-term performance of the membranes.
