Cathodic Protection is an Electro-Chemical technique in which the structure is protected against corrosion by applying an external current in a direction opposite to that of the corrosion current. The technique is used to protect existing as well as new structures. Cathodic Protection is applied to both steel and reinforced concrete structures using galvanic and impressed current systems.

CP division provides a complete cathodic protection engineering service for reinforced concrete and steel structures.

CP Division Engineers have extensive experience in the design and application of cathodic protection and marine anti-fouling systems to all types of buried and immersed structures. The Engineering Staff of CP Division have broad experience in theory and techniques used to evaluate corrosion mechanism, gather data necessary to determine a given corrosion control situation and to carry out the design, installationm testing and commissioning in the most cost effective manner.
SEC has extensive experience in various fields of CP System applications including:
