Sika FerroGard -903+

Sika FerroGard -903+ is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete. Sika FerroGard -903+ is based on organic compounds. Sika FerroGard -903+ penetrates the concrete and forms a protective mono-molecular layer on the surface of the reinforcing steel.

Protection with Sika FerroGard -903+ both delays the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika FerroGard -903+ 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.

  • 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 to prevent the development of incipient anodes
  • 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
  • Can be used as part of a simple yet effective concrete repair and protection system
