How To Repair Damaged Concrete

Concrete is known as one of the world’s most widely used durable construction products. It does, however, have its shortcomings and can unfortunately from time to time be susceptible to damage. So, how to repair damaged concrete? In most cases, it can be repaired, as long as you have the right skill set and technical know-how.

The repairs that are carried out to damaged concrete generally fall into two categories:

  • Damage arising out of Impact, overloading or fire damage.
  • Latent damage arising out of original design or construction deficiencies.

The recognised industry-wide standard for the repair of concrete is the British and European Standard BS EN 1504. This provides a set of valid working instruments that act as enablers to correctly identify defects and optimize resultant repair solutions. Here at Churchill Concrete Technology all our operatives are trained and experienced in the process and principles of BS EN 1504.

How To Repair Damaged Concrete? Let the experts help!

Once the cause of the damage to the concrete has been correctly identified, an accurate and appropriate repair solution can be readily worked up. A common, but false belief, that problems with damaged concrete can be resolved by removing the damaged areas and replacing with any type of repair mortar. This is not the case, defects should be carefully assessed by experts, and repair mortars carefully matched to the constituents of the original parent concrete.

The most common defect that causes damage to concrete that arises is the effects of Corrosion of Embedded Reinforcement. Corrosion to embedded reinforcing bars commonly occurs either as a result of Concrete Carbonation or through embedded, or induced, Chloride Attack.

When reinforcement steel is placed in concrete an iron-oxide protective film is created. This insulates the steel against the effects of oxygen and humidity and is formed around the steel. This occurs during the natural hydration process of the curing concrete. The protective film protects the embedded steel from corrosion. There are, however, factors that can seek to disrupt the protective layer around the reinforcing bar. These are commonly known as either ‘Concrete Carbonation’ or ‘Chloride Ion Attack’.

Factors that will allow the condition of the cast concrete to be disrupted by either Concrete Carbonation or Chloride Attack include:

  • Design shortfalls (cover and annotation of bar location),
  • Concrete mix specifications (water ratio content, aggregate selection)
  • Placing of concrete (compaction and curing)
  • Poor or perhaps even non-existent maintenance regimes following the initial installation of the original cast concrete.

Churchill Concrete Technology are here to help and advise on anything relating to how to Repair Damaged Concrete.
