Hydro-Vac 101: Understanding Hydro Excavation and Its Benefits

Hydro excavation has been in use since the mid-1800s when California miners would use steam pump pressurized water to mine minerals. A high-pressure water jet is used in the hydro excavation process to break up and remove material from below ground. Hydro Excavation is used for various purposes, including construction projects, environmental remediation, and archaeological excavations. In recent years, its popularity has grown due to its speed and safety compared to traditional blasting or heavy equipment use.

How Hydro Excavation Works

The hydro excavation work involves just three easy steps:

  1. The first step is to blast water or air into the ground to loosen the material and soften the ground
  2. Next, a hydro-excavator scoops up any loosened materials (slurry) and deposits them in prepared pans away from the hydro-excavation site. The step opens up a deeper layer of soil or any existing subsurface facility networks.
  3. Finally, when the work is complete, the open ground or the exposed underground network is covered with the slurry from the pans.

The Main Benefits of Hydrovac

Speed. Hydro excavation is much faster, taking only minutes to remove material from below the surface compared with hours or days for traditional methods like heavy equipment use and blasting.

Safety. The hydro excavator operator operates a machine that can be maneuvered into tight spaces and has minimal impact on surrounding structures because it doesn’t need anchoring or drilling into the ground. In addition, there are fewer risks because it does not use explosives or heavy equipment, which can cause dangerous situations with ground movement or vibration.

Efficiency. In addition to using less time and space, the hydro excavation also minimizes the disturbance of soils in a given area resulting from construction work – this is particularly important for archaeological excavations.

Environmentally friendly. Hydro Excavation is environmentally friendly because it doesn’t use any heavy machinery or fuel-dependent vehicles on site (so it doesn’t create any emissions). The process also has minimal disruption to the surrounding environment, which is especially important for commercial projects.”

Applications of Hydro-excavation;

Hydro excavation is preferred for its versatility for various uses, including

  • Pipe and sewer rehabilitation
  • Construction
  • Environmental remediation, and
  • Archaeological excavations.
  • Trenching
  • Potholing
  • tree stump removal.
