As conventionally reinforced coastal condominium buildings age, their susceptibility to chloride induced corrosion increases. Their proximity to the ocean allows salt laden air to be deposited on the structure. The salt migrates to the level of the reinforcing steel and corrosion is initiated. Traditional concrete repair techniques have proven to have relatively short lives in this aggressive environment. Cathodic protection has been successfully applied to these structures as a means of corrosion control. This paper discusses the corrosion process associated with steel reinforcing bars of multi-story condominiums located in coastal areas of Florida and the use of cathodic protection to control the corrosion process. The application of cathodic protection systems utilizing catalyzed titanium anodes, recommended design practices, and performance results are discussed.
