When concrete must be removed from under exposed rebar, our TracVac® unit is the ideal solution. It is a tracked machine weighing 1,700 lbs and will not damage or deflect the rebar. It is connected to our vacuum truck and to the truck’s water blaster (10,000 psi). The water blaster pushes the debris from beneath the rebar into the vacuum hood. This method of debris removal, especially from below the rebar is fast, efficient, cost effective and reduces the labor required on the project.
