Cathodic Protection

Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell.


Corrosion is one of the most common and expensive durability issues stakeholders encounter in both building and civil structures.

Corrosion is the process of deterioration of a substance or its properties as a result of a reaction within the environment.

Cathodic protection helps to prevent corrosion in steel reinforcement through an electrochemical technique that utilises an impressed current, galvanic system or hybrid solution.

The concept in the steel reinforcement acts as the cathode where no metal loss occurs, drawing all chloride ions towards the anode.
