Cathodic Protection

Cathodic protection can be applied in different ways, depending on the nature of the concrete structure and the degree of corrosion. There are two main forms:

Sacrificial anode system

This system uses anodes made of a less noble metal, such as zinc, aluminum or magnesium. These anodes corrode instead of the reinforcement, keeping the reinforcement protected. This type of system is relatively easy to install and does not require an external power source, making it especially suitable for smaller structures or applications with a low risk of corrosion.

INTEGRATED power system (ICCP).

In this system, an external power source is used to send a constant electric current through the structure. This current prevents corrosive reactions from taking place at the reinforcement. ICCP systems use durable, non-sacrificial anodes, such as titanium or graphite, and are suitable for large or highly deteriorated structures, such as bridges, tunnels and marine structures.

The choice of method depends on factors such as corrosion severity, environmental conditions, and the expected life of the solution.
