Corrosion inhibiting impregnation for steel reinforced concrete structures (improved formulation)

  • 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.
