Fastest, Most-Reliable Process to Excavate Congested Areas

The Hydro Excavation process provides a safer way to dig.  This process minimizes disruptions and damages to existing infrastructure. This process ensures that surrounding soil is not disturbed, reducing the cave-in fatalities.

What Is Hydro Excavation?

Premier Safe Digging Technologies

Hydro Excavation is the non-destructive process of removing soil to locate, expose, daylight, or safe dig utilities for potholing or relocating purposes. High pressure water is used to disturb the soil and create a slurry.  An industrial vacuum is then used to suction the slurry and expose deeper layers of the ground and any existing underground facility networks. Both the water and vacuum have varying levels of strength. The suctioned material is stored in the debris tank until it is transferred to an approved disposal location. Hydro Excavation is the safest, quickest, and most accurate way to locate utilities without the risk of damage, injuries, time, and money spent on repairs of utility strikes.

What are the benefits of using Hydrovac Excavation?

  • Safety: Reduces the risk of damaging underground utilities.

  • Precision: Allows for targeted excavation in congested areas.

  • Speed: Often faster than manual or mechanical digging methods.

  • Environmentally Friendly: Minimizes ground disturbance and restoration costs.

Common Applications of Hydro Excavatuion

Safely exposes underground utilities using pressurized water and vacuum extraction, giving crews clear visibility without damaging existing infrastructure.

Uses precise hydrovac technology to create clean, accurate holes for pilings, minimizing ground disturbance and ensuring structural stability.

Efficiently removes soil, slurry, and jobsite debris with high-powered vacuum extraction, keeping work areas clean and productive.

Reveals buried utilities without risk of strikes, ensuring accurate mapping and safer excavation planning.

Provides controlled trenching and soil removal to support safe pipeline installation while protecting adjacent utilities.

Excavates narrow, precise holes for utility poles, streetlights, and signage, reducing restoration needs and improving project efficiency.

Creates small, targeted test holes to confirm utility depth and location with minimal surface impact.

Supports sewer inspection and repair work by clearing access points and removing debris to prepare lines for maintenance and rehabilitation.

Delivers clean, accurate trenches for cables, pipelines, and conduit with reduced environmental impact and improved safety.
