Sika® FerroGard®-903 Plus

Active corrosion inhibitor for reinforced concrete

Sika® FerroGard®-903 Plus is a surface applied active corrosion inhibitor, based on organic compounds, designed for use as an impregnation of steel reinforced concrete. It penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel. Sika® FerroGard®-903 Plus both delays the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika® FerroGard®-903 Plus increases the service and maintenance life cycles by up to 15 years when used as a part of a complete Sika Concrete Repair and Protection System.

  • Suitable for method 11.3 (applying inhibitor to the concrete) defined by EN 1504-9 for Principle 11 (anodic control).

  • Does not alter the water vapour diffusion properties of concrete.
 
  • Long term protection and durability.
  • Can be applied to the surface of existing repairs and to surrounding areas.
  • Effective against carbonation.
  • Protects both cathodic (principle 9) and anodic (principle 11) zones of reinforcing steel.
  • Can be applied where other repair/prevention options are not viable.
  • Economic extension of the service life of reinforced concrete structures.
  • Easy, economical application, renewable.
