Abstract
A steeply inclined surface is hydrodemolished by providing a staging platform and a rig that includes a base frame defining a planar footprint within the frame. The rig is suspended from the platform by a cable such that frame is coplanar with the surface and the incline of the surface causes the rig to lean against it. Rails are provided on the surface to restrain spurious lateral movement of the rig. The rig is positioned on the surface and nozzles mounted on a trolley within a travelling carriage on the frame travel in two dimensions to hydrodemolish the surface within the footprint. The rig is moved vertically along the rails and laterally along the platform to reposition the rig to work a new section of the surface in conjunction with other rails that are also mounted on the surface.
