the machine can be used to clean or remove concrete, paint, rust and coatings from the inside of tunnels and pipes.

Working in conjunction with the company’s Aqua Cutter #hydrodemolition robots, the Aqua Centraliser is able to carry out these tasks along entire sections of tunnel, including inclined or vertical lengths.
