Hydro excavating is the safest, most cost effective and environmentally friendly method of excavating in the industry today. It is a process that utilizes pressurized water to break up and remove the soil via air conveyance into a debris tank providing a non-destructive means to safely locate utilities and precisely excavate an area.
