We use state-of-the-art, vacuum-based excavation systems, both trailer and truck based, to expose existing utilities. Our crews are available on an hourly basis, a unit price basis, or lump sum. The crews provide a complete scope of services including traffic control, asphalt/concrete restoration, and as-built documentation. Our state of the art rigs include both dry and wet vacuum systems for excavating in virtually all types of soil conditions. The dry vacuum uses high pressure compressed air to excavate native soil in a nominal 12” diameter hole and the vacuum system removes the spoils to a hopper for return to the hole after exposing the utility. In tighter ground conditions, high pressure water is used in lieu of air and the spoils are transferred to an 800 gallon tank for disposal off-site.
