Cathodic Protection Systems

Corrosion and the resulting deterioration it causes can dramatically reduce the service life  of vital infrastructure. Corrosion is a major cost to the economy, environment and if left  unchecked can become a serious safety risk.

CCI  uses electrochemical protection systems (EPS) to provide corrosion protection for  many types of structures across a range of industries including the following:

* Cathodic protection (CP) for existing concrete structures, including bridges, wharves  and buildings;

* Cathodic protection for steel structures, including reservoirs, pipelines and wharf piles

Introduction to Cathodic Protection

Galvanic or sacrificial anodes are designed with a more negative electrochemical  potential than the metal of the structure.

The voltage potential of the steel surface is  polarised (pushed) more negative until the surface of the structure has a uniform voltage   potential and the driving force for the corrosion reaction is halted. The sacrificial anode   continues to corrode (sacrifice), which consumes the anode material until it requires  replacement. The polarisation is caused by the current flow from the anode to the  cathode. The driving force for the CP current flow is the difference in electrochemical voltage potential between the anode and the cathode.

Corrosion Rate Monitoring | Corrosion Protection

We offer an extensive range of condition monitoring and lifecycle assessment products to ensure we offer the very latest in world leading technologies to our clients. CCI offers the latest technologies for monitoring corrosion in existing or new structures in concrete, water, air, soil and in oil and gas applications.


Vibration Analysis | Corrosion Protection

Measuring the overall vibration of a machine or component, a rotor in relation to a machine, or the structure of a machine and comparing the overall measurement to its normal value indicates the current health of the machine.A higher than normal overall vibration reading indicates that something is causing the machine or component to vibrate more.


Asset Assessment Reports | Corrosion Protection

Our Technical Division includes experienced industry professionals who have extensive experience in materials technology. Early investigation and diagnosis are essential to formulate effective asset protection or remediation strategies. We regularly provide these services to asset owners and managers across a range of industries. The deterioration of construction materials is both predictable and manageable.
