Air Vacuum Excavation
A Safe and Efficient Way to Locate Utilities
Air vacuum excavation uses high-pressure air (220 psi) to loosen soils and then a vacuum to pull it away into a tank. The vacuum pulls at a rate of 15 inches of mercury through a 4” line and deposits the soils in a tank that can hold 2.25 yards (450 gallons) of soil.
Air vacuum excavation is a much safer alternative to hand augering or hydro-knifing. It prevents a user from accidently grinding into a utility that was thought to be a rock or slicing into one with 3000 psi of high pressure water. It can prevent line damage and the expense of disposing of liquified soils.
Our team can work with public or private utility locators to safely daylight buried structures and utilities to prevent releases and disruption in services that may have occurred had it been struck by a traditional excavator. Once the physical location has been confirmed, soils can either be placed back in the hole, stockpiled or dumped into drums. Should the work area have many utilities, it can also be used to install shallow wells between lines that would be too close for conventional tools.
