Cathodic protection is still regarded as the only way of halting or controlling corrosion in steel and concrete structures.
It involves controlling the corrosion of steel through electrochemical cathodic protection.
Since introducing cathodic protection to New Zealand in the late 1980s, we’ve developed a great reputation for undertaking feasibility studies and designing, installing, testing, commissioning and monitoring systems using a variety of anode and control approaches.
Types of systems available include:
Together with our global associates, we’ve been involved in more than 40 installations in New Zealand and Australia. For advice on the right system for your project contact us today.
