Potholing (Also known as Non Destructive Digging, Vacuum Excavation and Hydro Excavation)
Potholing (also called non destructive digging, vacuum excavation and hydro excavation) is the process of digging holes in the ground using high pressure water blasters (similar to gernis) in conjunction with vacuuming up the mud slurry generated by the water blasting. This method of hole digging is essential for jobs where the location of underground services (electricity, water, telephone etc.) is unknown and electrocution or other dangers exist. Because only water and vacuum is used, the possibility of damaging existing services is removed making potential dangers jobs safe.
Potholing is also a safe and fast way to dig holes without taking up the large amount of room that mechanical diggers require. Lee’s Liquid Waste Services potholing equipment can park anywhere from 40m up to 150m away from the potholing location, rolling out the required meters of vacuum hose and water jetting reel from the vacuum excavation vehicle.
