Locating & Exposing Utilities
Hydro excavation is the safest and most efficient method of exposing underground utilities. Since it uses water to break up soil and vacuum up soil, water, and debris, it eliminates the risk of damaging underground utilities inherent with mechanical or manual excavation methods.
Using hydro excavation to locate and expose utilities, also referred to as potholing or daylighting, ensures that the surrounding soil or other material is undisturbed, while utilities remain undamaged and fully intact.
To expose utilities, Super Products’ Mud Dog® Hydro Excavators use a unique combination of pressurized water and an industrial-strength vacuum to break up soil and immediately evacuate the soil and water, all combined in one self-contained, mobile unit. Water is pressurized and injected into the ground through a handheld wand (much like a conventional pressure washer) to safely break up soil from the underground area. The resulting slurry of soil and water is vacuumed from the excavation site through a large debris hose connected to a debris tank, all in the mobile, self-contained unit.
Hydro excavation is not only faster, more cost-effective, and more accurate, but also less damaging to the surrounding soil than mechanical excavation (surrounding soil is virtually undisturbed during the process) and thus minimizes site restoration time and expenses.
In situations where utility lines are mismarked or not marked at all, leaving their location unknown, traditional excavation methods such as augers or hand digging can damage underground utilities, potentially causing project delays, safety hazards, and service interruptions. Hydro excavation can quickly and safely locate and expose utility lines without any of those risks.
Using slot trenching via hydro excavation, pipes can then be installed parallel or across existing utility lines, repairs can be made to existing lines, or new utility lines can be installed easier and quicker, without concerns for safety or service interruption.
