Hydro-excavation is a safe, non-destructive and cost-effective process that utilizes pressurized water to break up soil. The soil is then removed through an industrial strength vacuum into a debris tank. This process allows for safe and precise excavation, which requires less backfill and restoration, less labor and less environmental impact than traditional digging methods. Most importantly, hydro-excavation virtually eliminates the risk of damaging underground pipelines or utilities. Hydro-excavation is also commonly referred to as hydro-vac excavation, vacuum excavation, daylighting, water excavation, slot-trenching and potholing.
