What is Utility Locating?

Utility locating combines electromagnetic detection, ground-penetrating radar, and One-Call public utility marks into a single map of what's underground at a site. Hydrovac potholing is then used to physically verify critical lines at depth. Together, locating + potholing produces the SUE (Subsurface Utility Engineering) Quality Level A data that engineers and contractors need to design and dig safely.
