The first step in the selection of the most effective concrete repair technique is diagnosing the cause of failure, and ensuring that the technique used makes the repaired area resistant to this original cause of failure. If this is not done, the repair will fail; it is also likely that the damage will be extended to the adjoining parts of the structure.
