Potholing (Also known as Non Destructive Digging, NDD, Vacuum Excavation, Hydro Excavation & Vacuum Digging)
Non Destructive Digging (also known as vacuum excavation, hydro excavation, hydrovac and potholing) is the process of digging up 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 vacu digging is essential for jobs where the locating 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.
