Concrete bridge protection

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.

Requirements of Bridge Protection

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