When cathodic protection is selected as a rehabilitation method for a concrete structure, there are many choices that can influence the type, effectiveness, durability and cost of the system. If the structure is complex in design and exposed to a dynamic environment, proper selection of the system components is important for suitable performance and longevity of the system. In particular, the cathodic protection system should be selected keeping in mind the owner’s long term interests, maintenance capabilities and remaining design life of the structure. The purpose of this paper is to provide a general guideline to owners and engineers for proper selection of cathodic protection systems to overcome corrosion problems on reinforced and prestressed concrete structures.
