Non-Destructive Air-Vacuum Excavation is used to determine the exact horizontal and vertical location of any existing utility. This involves removing the surface material over approximately a 1’x 1’ to 1’x 2’ area at the electronically designated location. The air-vacuum process utilizes compressed air jets that simultaneously loosen soil while the vacuum extracts the debris, until the utility is uncovered. Since most contaminants move along utility line trenches, soil samples are taken for testing during the air-vacuum excavation process if requested by our clientele.

Non- Destructive Air-Vacuum Excavation can be performed laterally through the surface opening, if necessary. It can also be used at proposed boring location to excavate below the “utility window” (which is usually eight feet). This is useful when the mandated setback from existing utilities cannot be maintained or the location of the utilities is in question.

Non-Destructive Air-Vacuum Excavation is often used to map facilities and obtain soil samples adjacent to utility lines without risking damage.
