POTHOLING
Potholing using vacuum excavation is a nondestructive method of digging holes for many purposes. There is minimal amount of disturbance to the environment and very low risk of damaging existing structures in the ground.
Potholing with vacuum excavation reduces the risk of utility damage caused by striking an underground utility while digging.
Potholing can be utilized for:
Utility location / daylighting
Utility pole installation
Fence post installation
Footers
Piling holes
