HYDRO EXCAVATION

What Is Hydro Excavation?

Hydro excavation is a soil removing service. Instead of mechanical tools, the process uses pressurized water to create a dirt slurry. Hydrovac equipment can then vacuum the slurry to reveal deeper layers of the ground below. Crews commonly use this technique to uncover existing utility lines and pipe systems with minimal risk of breaks or tears.

How Hydrovac Works

First, hydrovac operators use high-pressure water wands to cut through the soil and soften the ground. Next, they suction the mud slurry into the tank of an excavation truck, at which point crews can uncover a deeper layer of soil and any existing underground facility networks. After the work is complete, they can release the slurry from the holding tank back onto the ground to cover once again the exposed subsurface facilities.

Hydrovac Applications

Hydrovac systems are used at a variety of work sites for construction, repairs, rehabilitation, and inspections. Specific applications include:

• Slot Trenching
• Daylighting
• Debris Removal
• Utility repairs
• Potholing
• Confined Digging
