Halt Corrosion
In Its Tracks

Cathodic Protection Is The Only Way To Control Corrosion

Cathodic protection is a tried-and-true method of halting or controlling corrosion in steel and concrete structures.


It involves controlling the corrosion of steel through electrochemical cathodic protection.

Contech introduced cathodic protection to New Zealand in the late 1980s. Since then, we have developed a great reputation for our work using a variety of anode and control approaches. Our team start with a feasibility study before designing, installing, testing, commissioning and monitoring a system to suit the project.


Together with our global associates, we have actively participated in more than 40 installations in New Zealand and Australia. For advice on the right system for your project contact us today.

Cathodic protection systems include

Hybrid Systems:

For maximum protection, we offer hybrid systems that combine both impressed and sacrificial methods. This comprehensive approach ensures your structures remain corrosion-free for years to come.

Impressed Systems:

These systems involve passing an electric current through the steel to prevent corrosion. It’s an effective method to safeguard your concrete structures against deterioration.

Sacrificial Systems:

In sacrificial systems, anodes are strategically installed to protect the steel. These sacrificial anodes corrode in place of the steel, offering long-lasting protection.
