Safe Digging

Safe digging, through a method called vacuum excavation or “soft dig”, is a non-mechanical and minimally invasive excavation technique.

How Safe Digging Works

High-pressure air or water is deployed to disintegrate and dislodge soil and break down large materials. An air vacuum hose is next utilized to extract the loosened soil into a holding tank. The accumulated soil is then segregated according to consistency. Dry soil can be repurposed for backfilling, while wet soil is transported to a designated off-site location.

Applications for Vacuum Excavation

Piloting or potholing to reveal underground utilities
Manhole and ducting installation in highly congested utility areas
Telecommunication manhole/pit cleaning
Precision hole digging
Mud and debris cleaning

Benefits of Vacuum Excavation

Vacuum excavation offers a more efficient alternative to manual excavation (hand digging) or bucket excavation, significantly reducing excavation time. It eliminates concerns of damaging cables or puncturing water pipes, which could lead to expensive repairs. Employing high-pressure air or water and a powerful vacuum, contractors would be able to safely operate around utilities without compromising their insulation.

Furthermore, vacuum excavation is suitable for “potholing” or “piloting” to expose underground utilities, particularly in densely congested utility zones where excavator buckets cannot access, and manual excavation poses risks to workers’ safety. This method is commonly applied to areas such as city centers, oil and gas plants, railworks, power stations, industrial plants, and airports.
