Bridge Deck Replacement using Hydrodemolition
Trenching Over Beams Via Hydrodemolition
Rampart Hydro Services has the technical expertise and advanced equipment required to help general contractors during projects that require bridge deck replacement. Hydrodemolition is not just for overlay projects, but can quickly and efficiently remove concrete to allow for bridge deck slab removal. We like to call this use of our equipment “trenching”, because we are creating deep, long pockets (or trenches) in the bridge deck. Our bridge deck replacement process removes concrete over the beams to expose the shear connectors, but does not damage the connectors or any other steel embedded in the concrete. This allows for easy removal of the bridge deck while maintaining the existing steel. This “trenching” option can be done on both steel and concrete beams where the specifications require the shear connectors not be damaged.
Mechanical methods of concrete removal (i.e. jackhammers) can damage shear connectors or other embedded steel that is supposed to remain intact. In addition, to remove concrete with jackhammers, the general contractor will need a team of people performing this labor-intensive task – a task that can cause worker injury. Our process, however, is one person and one machine. No heavy equipment to hold, no potential back injury – just one person operating a robotic machine. In addition, jackhammers produce silica dust. With OSHA’s new silica regulations, general contractors must consider the health effects of silica dust and the potential mitigation costs now more than ever before. Hydrodemolition does not produce silica dust!
