What is Hydro Excavation?

Hydro excavation is a modern alternative to traditional digging. Instead of heavy equipment that can damage utilities, we use water to break up soil and a vacuum to remove it. This process is precise, clean, and ideal for sensitive environments.

Applications of Hydro Excavation

Our hydro excavation services are used for:

  • Exposing utilities safely and efficiently
  • Daylighting underground pipes and cables
  • Trenching for water, sewer, and electrical lines
  • Potholing to verify utility locations
  • Catch basins, pits, floor drains, and manholes cleaning and maintenance

Benefits of Hydro Excavation

  • Non‑destructive: Protects existing utilities and reduces risk of costly damage
  • Efficient: Faster and cleaner than traditional digging methods
  • Versatile: Works in tight spaces, around structures, and in all soil types
  • Cost‑effective: Minimizes restoration costs by reducing property disruption
