Why Is Corrosion Protection Important?
Corrosion of steel reinforcement is one of the leading causes of concrete deterioration according to AMPP. If left unaddressed, it can compromise the structural integrity, reduce load-bearing capacity, and in severe cases lead to partial or complete failure. These outcomes not only result in high repair costs but can also pose serious risks to public safety.
Tailored Solutions for Every Environment
Freyssinet provides customized corrosion protection strategies designed around the unique needs of your structure. Whether it’s a bridge, building, tunnel, pipeline, or marine structure like a jetty or pier, we take into account your timeline, goals, and environmental conditions to recommend the most effective approach.
Our solutions target the area around the reinforcement or the steel itself and can be used to:
- Prevent the onset of corrosion
- Slow or halt early-stage corrosion
- Protect against long-term corrosion progression

A Complete Range of Services
Condition Assessment & Diagnosis
We conduct thorough inspections using a combination of non-destructive and intrusive testing methods to assess the cause, extent, and rate of deterioration. This evaluation also considers environmental severity and structural performance to determine remaining service life and load-bearing capacity.
Technical Studies
Our technical studies help identify the most suitable, long-term corrosion protection strategies based on your project’s performance goals, durability needs, budget, and timeline. Each solution is customized to ensure value and longevity.

+Electrochemical Treatment
This short-term, intensive corrosion protection method uses an electric field to neutralize corrosion activity. A sacrificial anode, embedded in an electrolyte gel applied to the surface of the concrete, creates an electric current directed at the reinforcing steel. A power supply regulates voltage to ensure safe and effective treatment.

+ Galvanic Protection
Galvanic protection is a well-established method for providing corrosion protection to steel reinforcement in concrete without the need for an external power source. The protective current is generated by the natural potential difference between steel and a zinc alloy anode. The zinc, being less stable, corrodes preferentially, protecting the steel and placing it in a state of electrochemical immunity.

+ Impressed Current Cathodic Protection (ICCP)
Impressed current cathodic protection is a highly effective method for preventing corrosion in reinforced concrete structures affected by chloride intrusion or carbonation. This system applies a controlled electrical current to the reinforcement, bringing the steel into an electrochemically immune state.
The performance of the corrosion protection system can be continuously monitored and fine-tuned by adjusting the polarization level of the steel (cathode), ensuring long-term reliability and effectiveness.
