Using high pressure water as a concrete removal technique is a good alternative to jackhammers. In order to remove deteriorated concrete, it is better to remove any previous concrete and replace it with new concrete to maintain the integrity of the structure. High pressure water can penetrate the pores of concrete and eliminate the structure with the highest pressure, creating an excellent smooth surface that is suitable for formwork. Not only does it not damage the structure’s reinforcement, but also it completely eliminates rust while keeping the metal intact at the end of the operation. The ear-splitting rattle of jackhammers can not only damage the operators’ hearing but can also cause severe pain, Hand-Arm Vibration Syndrome, and even permanent disability. Unlike jackhammers, water jet technology has solved these problems by providing qualified equipment which poses no danger to the operator.
