Why Choose Hydro-Excavation?

  • Hydrovac excavation is up to 10x faster and safer than hand-digging for potholing, reducing labor costs and utility strike risks.

  • The U.S. experiences 400,000 to 800,000 utility strikes annually, costing an average of $4,000 per incident in damage alone.

  • Traditional, non-vacuum excavation causes roughly 1,000 injuries and 75 deaths annually due to trench cave-ins.

  • High-pressure water and vacuum systems allow for faster, more precise excavation, such as locating a 6-inch pipe in 5 minutes.

  • Hydro Excavations results in less soil disruption and cleaner, more targeted excavation compared to conventional methods.
