Hydro excavation is the process of excavation, which is moving or removing soil, using pressurized water. The removed soil and water slurry is then vacuumed into a debris tank. This allows you to accurately excavate soil and locate underground utility lines or other underground items.
Hydro excavation uses pressurized wands to blast water onto the ground. This method has been very successful because you can adjust the pressure of the wands which allows you to remove soil in a relatively gentle manner. Ensuring that there is no damage to any utility lines or underground objects.
On top of this, hydro vac wands can also use hot water. This is critical in cold climate areas like Canada or the Northern United States. Where the soil is frozen and difficult to remove, hot water hydro vac excavation allows you to remove frozen soil and complete your excavation work successfully.
Safety Benefits of Hydro Excavation
Subsurface utilities are always needed for construction projects, or repairs. Excavation to install, access, or repair these lines is not an easy task. The versatility of the hydro excavation considerably reduces these risks, while keeping your costs low. At TEAM Group safety is our top priority, and our operators are well experienced in safe hydro excavation methods.
Hydrovac is more precise than airvac or manual digging, and also much safer. This has made hydrovac excavation one of the most popular methods of removing or cleaning ground.

How Hydro Excavation Works
Hydro vac excavation equipment combines high-pressure water (cold or hot) and an industrial vacuum with a secured debris tank. This equipment breaks up the ground, turns it into a slurry with the water, then the slurry is vacuumed up into the debris tank.
This involves 2 major pieces of equipment. The hydrovac wand, where the pressurized water comes from. This allows the operator to precisely target the excavation area. The second major piece is the vacuum truck, where a fan system or displacement blower is used to move huge amounts of air & slurry. The liquids and solids settle in the tank, and the excess air is blown back out.
