Concrete Repair Surveys

Concrete Repair Surveys

The reasons for the deterioration of concrete structures can be numerous, and could include carbonation, chloride attack, structural defects, poor design and poor workmanship etc. Therefore, to determine the most cost-effective remediation methods it is often prudent to carry out some initial survey work that may include visual survey, hammer test, cover meter survey, carbonation depth testing and laboratory sample testing to determine the presence of chloride and sulphates.
