When concrete has deteriorated or the reinforcing steel has begun to corrode, it is necessary to remove any unsound concrete and reinforcing bars (rebar) in order to replace it with new concrete and maintain the integrity of the structure. This process has also been used to remove sound concrete that is not compromised in any way.
If the concrete deteriorates or the steel reinforcement begins to corrode, it is necessary to eliminate unsound concrete and reinforcing bars (rebar) before replacing them with new concrete to maintain structural integrity. This approach has also been used to remove undamaged concrete that isn't compromised in any way.
