REINFORCEMENT CORROSION
Reinforced concrete structures exposed to marine environments or constructed with chloride contaminated aggregates or mixing water, are prone to chloride induced corrosion of the reinforcing steel. The corrosion that results from chloride attack causes spalling and large section losses on reinforcement and can result in significant damage or even collapse of structures if left un-treated. In these cases, the owners are faced with expensive and disruptive repairs to their structures.

CATHODIC PREVENTION
Cathodic Protection of new concrete structures, often referred to as Cathodic Prevention, is now widely recommended for new reinforced concrete structures that are to be exposed to chloride environments. The cathodic prevention systems are built in during construction to prevent corrosion of the reinforcement.

If well designed, installed and maintained the cathodic prevention system can provide an economically viable solution to minimize the total life cycle cost of new structures in aggressive environments.
