Advantages The process allows concrete to be removed to very precise depths and creates a uniform surface. Hydrodemolition also preserves reinforcement bars and does not introduce impact and vibration into a structure the way using a jackhammer would. There are also environmental benefits including reduced air and noise pollution. The water used during the demolition process can also be captured quickly and treated so as to reduce runoff contamination.

Hydrodemolition can be used for horizontal, vertical, and overhead concrete removal and surface preparation on reinforced and non-reinforced structures. It is effective in removing concrete from around embedded metal elements such as reinforcing steel, expansion joints, anchorages, conduits, shear connectors, and shear studs. Hydrodemolition can be used for localized removals where deterioration is confined to small areas and for large area removals in preparation for a bonded overlay. This tech
