Repeatedly, parking structures have strength, serviceability, and durability problems associated with their unique structural requirements and exposure to the elements. Many parking structures that are exposed to a deicer environment show very early signs of corrosion, scaling due to cyclic freeze-thaw damage, and through-slab water penetration. Special considerations are discussed to address the repeating problems resulting from design, construction, maintenance, and user practices. Methods used to evaluate conditions of existing structures are reviewed as well as the strategies employed for their future use. A breadth of maintenance, repair, and protection methods are discussed.
