WebMetallic structures in contact with water, soil, concrete, and moist air are subject to corrosion. Cathodic protection (CP) is one of the few methods that successfully mitigates corrosion. It can be applied in any situation where the environment surrounding the metal acts as a conductor for electric current. It has been successfully Websubject to corrosion if the soil resistivity is less than 700 Ω · cm indicative of a wet soil containing chlorides. Sandy soils have a high resistivity (more than 20,000 Ω · cm) and …
