CATHODIC PROTECTION OF REINFORCED CONCRETE DECKS COMPLETED IN NEW JERSEY

A total of 217,000 square feet of deck area is being protected from internal corrosion of the reinforcing steel by the application of impressed current cathodic protection systems in New Jersey. The details of the technique, which has eliminated repair of 79,000 square feet of deck area, is briefly summarized. Three different anodes have been used and represent the spectrum of anodes currently available on the market: two are carbon based, one is a two component rigid conductive polymer concrete, and one is a flexible conductive polymer strand. A state of the art remote monitoring system provides real time monitoring and data collection of the cathodic protection system. The cost of the systems averaged $8.50 per square foot. Based on the bid price of $30.00 per square foot of deck repair, a net saving of $570,000 was realized.
