Hydro excavation can be used to for a wide variety of purposes. It is most often used as a safe way to expose utilities. It’s important to regularly check utilities to make sure they are in their proper condition. It is also needed to see if there are parts that have been damaged. PowerVac is experienced with exposing utilities safely using hydro excavation.
Hydro excavation makes use of water to soften and break up the soil that is being removed. The soil is then transferred to the debris tank. This lessens the risk of damage to the buried utilities that sometimes happens when a manual excavation method is used. The process of hydro excavation in exposing utilities can also be called potholing or daylighting.
Hydro Excavation is a Non-Destructive Process
To expose the utilities, a combination of pressurized water and a vacuum is combined in one mobile unit. The water is injected into the ground by using a handheld wand to wash away the soil in the area safely.
A debris hose then transfers the soil to the debris tank. Because it is non-destructive, hydro excavation reduces the risk of damaging the underground pipes and cables. Using this method, the type, depth, and location of the utility is established accurately.
This method allows for clean, speedy and complete evacuations of the area that needs to be dug up. It requires less restoration, less backfill, less labor force and less negative environmental effects than typical digging processes. Accuracy is maintained because of the controlled flow of the water stream. Hydro excavation only removes the needed quantity of soil for examination and reparation of any problems in the utility lines.
