Concrete Repairs
Reinforced concrete structures strength can weaken when attacked from external elements such as freeze damage and erosion. Freeze damage occurs when frozen moisture expands within the structure during the thawing process.
If incorrect measurements are used in the concrete mix, a reaction with the water takes place to form silica gel, a material used to absorb moisture. This can cause concrete to crack and treating the problem can be complicated and it will make the structure look unslightly.
There are numerous techniques used for repairs to concrete structures:
- Hand Applied is used for small areas of carbonation on a building that requires isolated repairs. The concrete is worked behind the structural reinforcement by hand in layers.
- The recast technique is needed for large repairs or where large areas of reinforcement are located. Formwork and pouring sequences need to be quickly positioned before the bonding agent dries.
The repairs that are required depend on the level of the damage suffered, so far, clients can only be advised after a thorough appraisal. Once complete, a strategy of the repairs will be supplied to you outlining exactly what action needs to be taken and in what time scale they should be completed.
Spotting problems and treating them early is the key to keeping repair cost to a minimum and avoiding any further issues. Having regular maintenance checks to the structure for cracks and rust staining is also something we advise, this prevents further damage to structures affected by corrosion.
