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

Corrosion Protection Solutions

+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.

Electrochemical Chloride Extraction (Foreva® CL)

Chloride ions (introduced by coastal winds, deicing salts, or swimming pool water) can penetrate concrete and attack the steel reinforcement inside. The Foreva® CL system removes these chlorides by attracting them to an external anode while repelling them from the steel. The ions are captured in a surface-applied gel. Once chloride levels are reduced and the steel is repassivated, the surface is cleaned, dried, and sealed with a protective coating to prevent future contamination.
  • Directly addresses the root cause of corrosion
  • Promotes the re-passivation of reinforcing steel
  • Preserves the concrete’s original architectural finish

+ 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.

Galvanic Anode Options - Thermal Sprayed Zinc Anode (Foreva® GP Zinc)

This system involves spraying a sacrificial zinc anode directly onto the surface of the concrete to protect the embedded steel reinforcement.
  • No loss of structural clearance
  • No added weight
  • One-time, efficient installation

Discrete Anodes (Foreva® Galvastar)

For reinforcement with complex geometries, Foreva® Galvastar uses discrete zinc alloy anodes embedded into the concrete face.
  • Ideal for non-uniform or congested reinforcement layouts
  • Quick and simple installation
  • No additional weight added to the structure

+ 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.

ICCP System Variants – Discrete Anodes – Foreva® V+

This solution uses titanium mesh elements inserted into the concrete as discrete anodes for deep, targeted protection.
  • Provides in-depth corrosion protection
  • Suitable for areas with dense reinforcement
  • Works well with complex reinforcement layouts

Anodic Mesh – Foreva® CP Mesh

Layers of titanium mesh are installed on the concrete surface as active anodes. This system is compatible with dry shotcrete applications and ideal for harsh environments.
  • Effective for varying steel densities
  • Withstands aggressive environmental conditions
  • Can be applied in conjunction with dry shotcrete

Anodic Micro-Perforated Strip – Foreva® CP Ribbon

This system uses flexible, mesh-like titanium ribbons that adhere directly to the concrete surface to deliver surface-level protection.
  • Excellent adhesion to the concrete face
  • Suitable for a wide range of reinforcement densities
  • Designed for extreme environmental exposure
