Sika® Ferrogard® 903+

Embedded Steel

Sika® FerroGard® 903+ is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete and is an improved formulation of the original Sika® FerroGard® 903.

 

Sika® FerroGard® 903+ is based on organic 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 a part of a complete Sika Concrete Repair and Protection System.

Uses

  • 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.

 

Characteristics and Advantages

  • 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

Sika® Margel VPI 580

Sika® Margel VPI 580 is a patented vapour phase corrosion inhibitor which is inserted inside concrete structural elements close to the reinforcing steel. The product has been specifically developed to ensure the corrosion inhibitors are released over a period of 12-48 months. This results in a well bonded layer of corrosion inhibitor around the reinforcing steel resulting in a passivated protective layer that reduces exposure to chlorides, water and oxygen.

Uses

  • Reinforced concrete deteriorating from corrosion
  • Where coatings have been applied and surface applied corrosion inhibitors cannot penetrate
  • Car parks and bridge decks
  • Protecting reinforcement at greater depths than surface applied corrosion inhibitors can penetrate
  • Chloride contaminated concrete
  • Carbonated concrete
  • Historic structures

 

Characteristics and Advantages

  • Proven technology – 25 year track record.
  • Focused protection - provides localised protection where actual and potential corrosion risks are high.
  • Economical - low cost method protecting local areas of reinforcement that are chloride contaminated or contained in carbonated sound concrete, thereby reducing concrete breakout.
  • Versatile - effective in chloride-contaminated and carbonated concrete.
  • User friendly - installation is quick and easy.
  • Low maintenance – requires no external power source or system monitoring.
  • Long lasting – 10 to 20 year service life reduces the need for future repairs.
  • Full system – can be used in conjunction with Sika® FerroGard®, Sika® Galvashield®, Sika® Ebonex® & Sikagard® coating technologies to offer a full Total Corrosion Management System.
