Why Do Bridges Need Protecting?

To improve the performance and durability of reinforced concrete surfaces on bridge structures, additional protection systems are frequently required, particularly in refurbishment situations. Typical concrete protection systems for bridges can be classified as hydrophobic impregnations, sealing impregnations, surface coatings, or corrosion inhibitors. These are designed for use in different situations or collectively in alternative combinations, to greatly reduce damage to theconcrete surfaces and to stop or significantly reduce the rate of steel reinforcement corrosion. Thus preventing the even more significant structural damage, that would otherwise occur.


  • Protection against ingress of water, chloride and carbon dioxide
  • High resistance against UV radiation
  • Resistance against frost and wide temperature variations

Sika's Bridge Protection Products

Sika provides a wide range of tested and well proven concrete protection systems based on different technologies including hydrophobic impregnations, impregnations, rigid and elastic surface coatings, plus surface applied corrosion inhibitors. All of these Sika products and systems fully comply with various standards and regulations.

Total Corrosion Management - Future Proofing Bridges from Further Corrosion

Sika® Ferrogard® 903+

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.
