Summary During concrete removal around reinforcement@ including unbonded post-tensioned systems@ potential collateral damage to the repaired structure must be considered relative to future performance. Consequently@ selection of the appropriate method of concrete removal is crucial. Hydrodemolition is not recommended for concrete removal if there is a possibility that unbonded post-tensioned systems are within the concrete removal zone.
