Hydro Excavation

At Diversified Underground we work hard to hold on to our roots. To us diversity means not only having a versatile workforce, but it also means having the right tool for the job. In saying this, we realize that the most hydro-excavation projects can be done with smaller vac trucks – which are more economical and maneuverable, but sometimes digging conditions are extremely difficult with large rocks, hard soil, or a high water table – just to name a few. When you run into these difficult digging situations we also take care of you with our fleet of large vacuum units.

What is Hydro-Vac Excavation?

Hydro-Vac Excavation (Utility Potholing or Daylighting) is based on a combination of water-blasting and vacuum power to provide non-destructive excavating of buried pipes, lines and other structures requiring gentle removal of soil. Water from the Hydro-Vac is pressurized and delivered through a handheld wand to loosen the soil. The resulting slurry (composed of water and earth) is sucked up in a debris hose by the powerful vacuum system and stored in the vehicle’s debris tank. A visual observation of the buried underground structure can now be accomplished and the pipes, lines or other structures identified and repairs completed.

Benefits of Hydro-Vac Excavation:

  • Provides a safer and more efficient method to excavate buried utilities.
  • Enables a visual confirmation of surface locate marks.
  • Minimizes ground disturbance and reduces site restoration costs.
  • Eliminates the need for hand excavation, reducing damage to buried underground structures and possible worker injuries and tens of thousands of dollars in insurance claims.
