Hydro Excavation

Hydro Excavation in London, Ontario

The process of Hydro Excavation, the only non-destructive method of digging, utilizes pressurized water and a vacuum system to quickly and safely expose underground infrastructure.

During the hydrovac process, pressurized water is injected into the ground through a handheld wand. As the soil cover is liquefied, the resulting slurry is simultaneously extracted by a powerful vacuum and stored in a 14 yard debris tank onboard the hydrovac.

Hydrovacs can dig effectively in all soil types, including clay, and with the aid of onboard heaters, hydrovacs provide a safe means of digging in frozen ground.
