COATINGS AND CATHODIC PROTECTION OF PILINGS IN SEAWATER: RESULTS OF 5-YEAR EXPOSURE

This report presents the results of the inspection of test pilings extracted after 5 years of exposure to seawater at La Costa Island, Fl. The effectiveness of various coating systems and sacrificiacl anodes in preventing corrosion of H- and steel pipe pilings in seawater is assessed. Six of the coating systems were found to perform excellently, as was a coating/cathodic protection combination. Sacrificial anodes of zinc and aluminum were also found to effectively reduce corrosion in the immersed zone. /Author/
