Partial Depth Removal and Rebar Exposure Cleanup using our TracVac® and VAC+HPW.
If rebar exposure or partial depth hydrodemolition is performed, the concrete from around the rebar is removed and the rebar is typically left unsupported. It is not safe to drive equipment on the exposed rebar as this will damage or bend the rebar. In addition, the hydrodemolished concrete is below the rebar making it very difficult to remove. To perform this specialized cleanup, Rampart developed the TracVac® machine.
When connected to our VAC+HPW custom vacuum trucks, the TracVac® can vacuum up debris from below and around the rebar. The TracVac head moves back and forth over the rebar and debris. The 10,000-psi water blaster in the VAC+HPW truck blast the debris from the surface and into the vacuum hood.
The TracVac is a light weight (1700 lbs.) rubber tracked machine. While the rebar is unsupported by concrete, it is still supported by the original chairs or carrying bars. The rebar can easily support the weight of the TracVac. The unit does not bend or damage the rebar.
Vacuuming hydrodemolition debris is fast and efficient. The vacuum system can clean up the debris as quickly as the hydrodemolition robot will produce it. Clean up can be completed in a timely manner, ensuring that the debris does not re-solidify. Using the TracVac system, the debris and residual wastewater can be easily removed from around the rebar.
Rampart can provide a complete concrete removal package including hydrodemolition, water supply, debris collection, wastewater collection, and wastewater treatment.
