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.
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
- 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
