In 2013, the Palmetto Health parking garage in Columbia, South Carolina, was in need of repair. The garage occupies much of a city block with six levels of constantly used self-parking. Like most parking structures built in the 70s and expanded in the 80s, the weatherproofing had failed, resulting in structural and safety issues. These included concrete cracking and spalling, corrosion of structural connections, and considerable floor slab leakage. In addition to the water leakage, the structural issues were evident by the noise generated as vehicles drove through the garage
WTI and licensed engineering firm O&S Associates performed a condition survey and presented repair and preventive maintenance options to maintain and extend the life of the garage. The result was a phased restoration plan that spread the costs over seven years, lessening the impact on the annual operating budget. A true team effort, WTI, Tremco Roofing and Tremco Commercial Sealants and Waterproofing personnel worked together to create and deliver the solution. Year two is now complete, with repairs to continue.

Year Two included
The project’s first two years were completed on time and on budget, with minimal disruption. WTI’s work and traffic plan management kept vehicle and pedestrian traffic open while limited areas were closed as work was performed. Today, there is no more water leakage or vehicle noise on the upper level where structural repairs have been completed.
