Hydrovac Process

Hydro excavation is used in place of mechanical methods to help expose underground utilities. It can reduce a lot of the risks and costs associated with locating utilities with traditional excavation methods. Mechanical methods may cause delays, safety hazards, and possibly service interruptions from damage.

A piece of equipment, often called a hydrovac combines high-pressure water with an air vacuum. Because the water is highly pressurized, it can break through soils, and the vacuum then lifts the slurry from the excavation area into a debris tank. The underground utilities are then exposed.

The hydro excavation process reduces many unnecessary effects from traditional excavation methods, eliminating damage to the surrounding pipes and utilities. Damage to the environment is considerably lessened and only removes the needed quantity of soil.
