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. The types of Hydro Blast Cleaning provided by JonNestor are Airblast & Wetblast, Hydromilling, Waterblasting, Waterjetting, Cold Cutting.

This process has also been used to remove sound concrete that is not compromised in any way. This may be done to install a preventive cathodic protection system, or to remove concrete in structures in which vibration is a concern. Unlike jackhammers, hydro-demolition does not produce vibrations throughout a structure and therefore does not introduce micro fractures.
