Robotic Crawler Hydroblasting is a surface preparation device with highly mobile, self-affixing surface preparation device. The technology emphasizes on the environmental friendly equipment that utilized the techniques for cleaning surface relies entirely on the energy of watet striking of pressurized water directed through a 16 nozzle to impact of surface with no media/abrasive/inhibitor used. Hydro blasting is performed with maximum pressure above 35,000 psi.
