Air Knife Vacuum Truck and Utility Locating Equipment

At most drill sites, concerns exist about potential underground utilities or obstructions. Drilling into utilities or obstructions carries safety risks, can result in costly repairs and cause project delays. There is an easy solution for uncovering utilities and obstructions before drilling begins. At the borehole location, use our air knife vacuum truck to air excavate ("pothole") or probe to a depth of up to 12 feet to physically locate utilities and obstructions.

The air knife vacuum truck safely uncovers underground utilities and obstructions. It quickly digs deep down with air, locating underground utilities in the hardest soils without harming them.

Even if a drill site has been cleared by a utility locating service, it is wise to use an air knife vacuum excavation system to further minimize the risk of drilling into a utility. Utility locating services have been known to mislocate and mismark subsurface utilities for a variety of reasons.
