Hawk Drilling is well aware of the dangers that underground utilities pose to drilling operations. To cope with this problem we offer Air Knifing and Soft Dig Vacuum Excavation capabilities to our clients.
This technique is typically used to pre-clear a borehole in an effort to expose buried utilities. Vacuum excavation/air knifing utilizes a high pressure air to penetrate, expand and break-up soil. Loose soil and rocks are then vacuumed directly into a drum. Upon completion of the borehole, the contents which were removed are then deposited back in the boring. When utilized properly the method is a safe, non-destructive means of excavation.
