Cathodic prevention (CPrev) of reinforced concrete structures is used to improve the corrosion resistance of reinforcement for marine structures that are expected to suffer from chloride-induced corrosion during their service life. As a part of a major rehabilitation programme to the Sydney Opera House during 1995-1996, a CPrev system was installed to the reinforced concrete pre-cast elements of the Western Underbroadwalk of the Sydney Opera House.

This paper will assess the cathodic prevention system performance after nearly 10 years of operation and will make a comparison between the designed and operating cathodic prevention current density of the system.
