When cracks or damage to concrete surfaces occur, it is important to address them promptly to avoid further deterioration and more costly repair. There are a variety of methods available for repairing concrete, and the choice will depend on the type of damage, the cause, and the desired level of strength. A professional contractor can help assess the condition of the concrete and determine the best repair method. They will also be able to guide preventative maintenance and can assist with the preparation of a contract for the repairs.Source :https://concrete-repair.uk

When repairing existing concrete, the condition of the surface should be assessed to ensure that the new materials will bond to the existing concrete and not delaminate. The surface must be free of dirt, rust, and other contaminants. This will enable the crack fillers to penetrate the crack and establish a strong bond with the existing concrete. It is also necessary that the concrete have a low shrinkage rate to minimize cracking of the repair.

Common Concrete Repair Issues and How to Fix Them

Stitching concrete cracks involves drilling entry and exit holes across the crack and running a series of U-shaped metal staples to bridge the gap. This is a non-disruptive method of repairing concrete, and it provides long-lasting and cost-effective results.

Conventional placement of concrete is the most common repair method. The repair concrete must have a low w/c and a high percentage of coarse aggregate to minimize shrinkage cracking. A quality concrete mix will also have a low thermal stress due to temperature change and should be placed with an adequate slump.
