Air vac

By using a high pressure air vac to dig instead of water, we are able to recycle the soil back into the ground without outside contamination or by adding any volume to the fill. The debris from the air vac remains dry and can be immediately used for backfill or stored for later use. It does not need to be hauled away to an approved dump site which costs time and money and it does not create a wet mud hole when dumped. Our air vac uses large dump bucket tilts from the side and drops the soil in a manageable sized pile on the job site.
