Hydro-demolition uses high-pressurized water to eliminate damaged concrete. This technique is also used for asphalt and grout. Hydro-blasting efficiently removes the material from metal, it gets rid of the damaged concrete while leaving the good quality material intact of reinforced steel, expansion joints, connectors, studs, etc. Meanwhile, high-pressure blasting creates a better bonding surface for new materials to affix to.
Industries examples: Construction, etc.
Advantages of using high-pressure water:
1. No dust pollution and less noise pollution than other methods
2. Water collected and disposed in an environmentally safe manner
