Concrete problems and deficiencies are caused by many factors. Water and moisture intrusion, freezing and thawing and excessive loading are common causes leading to failures in concrete. Concrete repair replaces defective, damaged, or deteriorated concrete; restores structural function; protects the surface or underlying concrete from aggressive environments; and restores any lost performance requirements.
It is important to understand the cause when developing a proper repair procedure so that the repair will result in extending the life of the structure or element. In all cases, the repair procedure must consider the appearance, protection needs, load carrying requirements and cost. The American Concrete Institute and the International Concrete Repair Institute state that surface preparation is one of the key elements to success and long term repairs. Proper surface preparation includes complete removal of deteriorated concrete around and below the reinforcing steel and preparation of the substrate. Preparation of the substrate and steel can include water blasting or sand blasting. Effective repair procedures usually draw from a variety of repair materials such as mortars having performance properties designed for specific applications. Each class of materials delivers a level of performance and protection as part of the overall repair strategy.
