Hydrodemolition is a technology that removes concrete selectively with high-pressure water without causing damage to the remaining structure. “Selectively” means that the weak concrete is removed down to a pre-set quality level while the good concrete remains.
The technology is mainly used on sensitive structures such as bridges, tunnels, parking decks, dams, locks, and canals.
The tool is a robot that removes the concrete, and the removal process is controlled remotely by an operator.
The unit that removes the concrete consists of a special hydrodemolition robot that moves a highpressure water lance along a feed beam at a certain speed and pattern. Further is a large high-pressure pump creating the flow and the water pressure for the lance mounted on the robot.
