Exposing Utilities

Hydro excavation is the safest and most efficient method of exposing underground utilities. Since it uses water to break up ground and vacuum up debris, it eliminates the risk of damaging buried utilities inherent with mechanical or manual excavation methods. Using hydro excavation to expose utilities, which is called potholing or daylighting, ensures that the surrounding material is undisturbed.

To expose utilities, Super Products’ Mud Dog Hydro Excavator uses a unique combination of water pressure and vacuum, combined in one self-contained mobile unit. Water is pressurized and injected into the ground through a handheld wand to safely wash soil from the underground area. The resulting slurry is vacuumed from the excavation through a large debris hose connected to a debris tank.

Since it is a non-destructive process, hydro excavation eliminates the risk of damage to buried cables and pipes. Using hydro excavation enables the location, type, and depth of the utility to be accurately established.

Not only is hydro excavation faster and more accurate, but it also does less damage to the surrounding soil than mechanical excavation and thus minimizes site restoration time and expense.

In instances where utility lines are mismarked or their location is unknown, using traditional excavation methods such as augers or hand digging can cause potential delays, safety hazards, and service interruptions. Hydro excavation can quickly and safely expose utility lines without those risks. Pipes can then be installed parallel or across existing lines, repairs made to existing lines, or new utility lines installed without safety or service concerns.
