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

Corrosion is the deterioration of a substance or its properties due to environmental reactions.

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 is to make steel reinforcement acts as the cathode where no metal loss occurs, drawing all chloride ions towards the anode.
