Pot Holing is the hydro excavation technique used to locate subsurface utilities when the exact position of the utility is known.

Potholing is most often used when a contractor needs to verify the depth, size or type of underground utility or to check for any damage such as punctures and cracks.

Traditionally, this was done with labor-intensive, time-consuming manual labour. This was not the least bit efficient and also presented serious risk of damage to utilities and or equipment.  Hydro excavation is now the preferred method for potholing or daylighting.

In addition to uncovering buried utilities, Potholing is also an efficient and cost effective digging method for any installation (including signs, telephone poles, fences, etc.)
