Sika® Ferrogard 901

Sika® FerroGard®-901S is a liquid concrete admixture based on Sika® FerroGard® Technology for use in reinforced concrete and mortar. It acts as a corrosion inhibitor for the steel reinforcement. By using Sika® FerroGard®-901S, the life expectancy and durability will be substantially increased.


Sika® FerroGard®-901S is designed for reinforced concrete particularly at risk of corrosion. It specifically provides protection from chloride induced corrosion.

Typical uses are in:

  • Concrete roads
  • Bridges
  • Tunnels
  • Retaining walls
  • Industrial plants
  • Multi-storey car parks


By using Sika® FerroGard®-901S both the anodic and cathodic reactions of the electrochemical corrosion process are reduced. The product forms a film on the steel surface which delays the onset of corrosion and also reduces the rate of corrosion.

Sika® FerroGard®-901S is a combination of organic corrosion inhibitors.

The following advantages can be achieved using Sika® FerroGard®-901S

  • Corrosion protection for embedded reinforcing steel, especially from chloride attack
  • Protection from the destructive influences of reinforcement corrosion
  • No negative influences on the properties of both the fresh and the hardened concrete

Sika® FerroGard®-901S is neutral to hydrogen embrittlement of prestressed steel i.e. it neither enhances nor limits hydrogen embrittlement of prestressing steel
