WHAT IS CORROSION?
Corrosion refers to a natural process that gradually destroys materials due to various chemical or electrochemical reactions that happen in the environment. Corrosion protection is essential in acting as a barrier to protect this process from occurring. Sika has a variety of anti-corrosion agents that can prevent this process from happening. As the global leader in concrete repair and protection, corrosion inhibition and structural strengthening systems, Sika can bring these combined resources together to support your project requirements for corrosion management. All are supported by the most highly trained and experienced sales and technical support network in the industry. Our products include:
SIKA'S FULL SYSTEM OF REPAIR AND PROTECTION PRODUCTS
Anodes
Zinc based, discrete, sacrificial anodes placed inside a concrete repair area in reinforced concrete structures which are corroding as a result of chloride induced corrosion.
Corrosion Inhibitor
Zinc based, discrete, sacrificial anodes placed inside a concrete repair area in reinforced concrete structures which are corroding as a result of chloride induced corrosion.
Silanes
One part, low viscosity, solvent free, reactive hydrophobic impregnations for concrete, masonry and cementitious substrates based on silane technology.
Rebar Coatings
1 or 3-component, cementitious, epoxy or zinc based coating materials with integral corrosion inhibitor, used as bonding primer and reinforcement corrosion protection.

| Product | Best Use | Target |
|---|---|---|
| Sika FerroGard901 | New Construction and admixture to any repair mortar | Protect anodes and cathodes throughout the structure or “ring anode” and added protection in repairs |
| Sika CNI | New Construction | Protect anodes throughout the structure |
| Sika FerroGard 903 | Low to medium chlorides, carbonation, early maintenance, ring-anode treatment, reduce moderate existing corrosion | Protect anodes and cathodes throughout the structure, reduce active corrosion |
| Sikagard Coatings | Preventative on existing structures. Supplement to Sika FerroGard 903 and Sika Galvashield | Prevent ingress of chlorides, carbonation and water |
Ignoring Corrosion is NOT an option - corrosion grows over time
- 3% of GDP each year attributed to corrosion
- 27.5% of US bridges are structurally deficient or functionally obsolete
- Condition of infrastructure rated a D+ by ASCE

Start with the condition survey
A thorough condition survey is critical to ensure a successful repair & protection project. This testing should always be conducted by a qualified professional. Surveys generally consist of performing any number of the following tests:
- Spall and delamination survey
- Chloride and carbonation testing
- Reinforcement mapping and cover measurements
- Half-cell potential contour mapping
- Corrosion rate assessment
