Cathodic protection (CP) has gained increasing acceptance on multi-level reinforced concrete parking garages to combat the spread of corrosion caused by deicing salts. This article describes its application on the Dane County Parking Ramp, located in Madison, Wisconsin. The seven-story facility was built in 1957 and expanded in 1963. With capacity for 1,000 cars, the garage provides dedicated levels for city and local utility employees, guest parking for a nearby hotel, and metered parking for transient users. In the early 1970s, cracking and spalling developed along the heavily trafficked ramps and drive lanes. Conventional methods were unsuccessful in halting progressive delamination. Included in this article is information on the consultants' findings on the extent of damage, comparison studies using life-cycle cost analysis of CP and several competing methods, and the restoration strategy.
