STRUCTURAL CONCRETE REPAIRS

Concrete spalling is a condition wherein your concrete develops a series of scales or large concrete chips. The spalled surface appears to crumble away from the surrounding concrete. Spalling is generally caused by carbonation of the concrete where carbon dioxide reacts to chemicals within the concrete. The steel reinforcing bars within the concrete begin to corrode and expand, causing the breakage on the surface concrete. If caught early, spalling can be repaired, removing the need for complete concrete replacement.

Concrete spalling repairs can be proceeded under The Minor Works Control System (MWCS), which has been fully implemented since 31 December 2010. In order not to violate the legal requirements of the new system, any member of the public intending to carry out minor works should employ prescribed building professionals (PBP) and/or prescribed registered contractors (PRC) to do so.
