What is Hydro-Excavation?
This type of excavation is also called "vacuum excavation", "potholing", "hydro-digging", "hydro-trenching" or "soft digging". The basic process is always the same, pressurized water or air and a vacuum source to remove the material.

Hydro-Excavation is a non-mechanical and non-destructive process which combines pressurized water and a high flow of moving air to simultaneously excavate and evacuate native soils at a controlled rate. The soil and water slurry are conveyed via an 8" tube to a truck-mounted debris tank. This process allows for quick, clean and precise evacuations which require less backfill, less labor force, less restoration, and less environmental impact than conventional digging methods. A controlled flow water stream allows for surgeon-like accuracy. While removing only material necessary for repair or inspection, minimal material needs to be removed when compared with the large, less-than-accurate excavator or back hoe bucket.

A Hydro-Excavator is a completely self-contained unit which is comprised of several pieces of equipment. The complete package is absolutely necessary to provide the most efficient service to the customer.
