Vacuum Excavation – also known as “daylighting”, is the non-destructive process of using high pressure streams of water or air to break up ground and excavate while simultaneously using a high air flow vacuum which sucks up the soil, debris, dirt, rock, etc. – thereby allowing a visual observation of the buried underground utilities or infrastructure.
The process is safer, faster, non-destructive and “more telling” than any other method of excavation or locating.
The process delivers a safe, clean and precise excavation while eliminating potential damage to the buried utility, underground infrastructure or facility.
Qualis advantages include:
- Excavate in congested or sensitive areas
- Excavate 300’ from dig site
- Excavate 35’ beneath ground
- Minimize ground disturbance
- Reduce site restoration costs
- Assist backhoes or mechanical equipment
