Structural Concrete Patching

Structural Concrete Patching

Structural Concrete Patching

The patching of concrete, particularly structural concrete, involves much more than slapping some patching mortar into a delaminated area. Almost always the delamination was caused by water corrosion and subsequent expansion of the imbedded structural steel.

As with any repair solution, understanding the root cause and proper preparation are crucial to the longevity of the repair. For the successful patching of concrete, one must avoid featheredging of any patching material, and properly clean and treat the corroded steel. This involves removing all unsound concrete, saw-cutting and removing the sound concrete to create a perimeter shoulder, and fully exposing the corroded steel. The steel should then be cleaned of all rust and coated with rust inhibitor prior to installing any patching mortars.

Other types of concrete repair include the use of epoxy injected resins and carbon fiber wraps. These solutions are more technical in nature and are always done under the guidance of a structural engineer.
