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 and inorganic compounds. Sika FerroGard-903 penetrates the concrete and forms a protective monomolecular 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 part of a complete Sika Concrete Repair and Protection System.

  • Complies to principle 11 of EN 1504-9 method 11.3 (applying inhibitor to the concrete)
  • Does not change the appearance of the concrete structure
  • 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
  • Penetration depth can be tested on site using the Sika “Qualitative Analysis Test” - refer to your local Technical Service Department for details

Usage

  • For the corrosion protection of steel reinforced concrete structures above and below the ground
  • As a corrosion control treatment for undamaged reinforced concrete where reinforcing steel is corroding, or is at risk from corrosion due to the effects of carbonated or chloride contaminated concrete
  • Sika® Ferrogard®-903+ is especially suitable for extending the service life of aesthetically valuable fair-faced concrete surfaces such as historic structures
