High Pressure Water Jetting

High pressure water jetting is a concrete removal technique mainly to remove deteriorated concrete, and tiles. Different from jackhammers and drill hammers, high pressure water jetting does not produce structural impact, and hence, less structure borne noise transmission, less damage to the building structure and less noise emission. It can be applied inside inhabited building.
