VACUUM EXCAVATION

Capabilities

Vacuum excavation technology utilizes a three lobe blower to create a vacuum within a contained space. Through the use of filters located inside the vacuum container, dirt, water, and other materials are kept inside the container for removal or for placement as backfill. Through the use of 4”, 6”, and 8” vacuum hoses, the excavated material is vacuumed from the excavation site. A 150 cfm air compressor utilizes an air lance to break up solid formations that are intended to be excavated. A similar process utilizes water flow at 3,500 psi to break up sever solids and is used for very specific applications. The use of vacuum technology results in non-destructive excavation that is harmless to existing utilities and allow for work in small confined spaces. The vacuum truck can excavate vertical holes 4–inches in diameter or larger. This can provide for small pavement patches to be taken or for larger vertical holes to be made (for which Goudy Engineering, Inc. can also provide casing).

Goudy Engineering, Inc. can mark underground utilities using electronic locating equipment. In the case of an excavation, the Vacuum Truck is useful in that other standard excavation methods can be extremely hazardous to the excavated utility, causing severe damage. Performing vacuum excavation with our Vacuum Truck will never damage the utility.
