Corrosion in reinforced concrete parking garages is reaching crisis proportions. The rehabilitation market for these structures is estimated to be as much as $750 million a year, or 30% of the $2.1 billion spent now each year for design and construction of these facilities. The problem is worse where deicing salts are used in northern climates and in coastal areas where marine salts reach the reinforcing steel. Cathodic protection, an electrolytic process, is a proven anti-corrosion technoque. The method has long been used in piplines, more recently to protect bridge decks and is now being used in parking garages. The Federal Highway Administration officially supports the technology for bridge decks and their approval has hastened acceptance for the parking garage market. Case histories are included with comments from consulting engineers and suppliers.
