What is Hydro
Excavation?
Hydro excavation is a non-destructive excavation method that uses pressurized water and a powerful vacuum system to safely remove soil in sensitive or congested areas. Pressurized water breaks up the soil, creating a slurry that is immediately vacuumed into the hydrovac truck's debris tank. This precise process minimizes ground disturbance while protecting surrounding infrastructure.
The collected slurry is then transported to a licensed soil recycling facility, where the soil is separated from the water and responsibly recycled or repurposed.
Hydro excavation became widely adopted in Canada, where heated water systems made it possible to safely excavate frozen ground during harsh winters. Today, it is a trusted solution across the utility, municipal, construction, telecommunications, and energy industries for its precision, safety, and efficiency.
Benefits of Hydro Excavation
Hydro excavation offers several advantages over traditional excavation methods, making it the preferred choice for many construction and utility projects.
-
Accessibility – Reaches confined or hard-to-access areas while allowing excavation to be completed away from the truck using an extended vacuum hose.
-
Precision – Uses adjustable water pressure for accurate, controlled excavation with minimal ground disturbance and cleanup.
-
Enhanced Safety – Reduces the risk of damage to underground utilities, surrounding infrastructure, and personnel.
-
Greater Efficiency – Completes projects faster by minimizing delays, reducing restoration work, and improving productivity.
-
Year-Round Operation – Heated water systems allow safe excavation in frozen ground, keeping projects moving through the winter.
-
Cost Savings – Lowers overall project costs by reducing utility damage, restoration requirements, environmental impact, and downtime.
A Safer Way to Excavate
While hydro excavation offers many advantages, its greatest benefit is safety. As a non-destructive excavation method, it allows crews to safely excavate around underground utilities with significantly less risk of damaging infrastructure or endangering workers compared to traditional mechanical excavation.
The statistics reinforce this advantage. In 2016, hydro excavation accounted for just 0.2% of excavation-related accidents, compared to 40% of accidents involving backhoes and trenchers. In 2017, more than 400,000 excavation accidents were reported across North America. These figures highlight the importance of choosing safer excavation methods and demonstrate why hydro excavation has become the preferred solution for projects involving underground utilities and other sensitive environments.
