Cable location vs hydro excavation: which do you actually need?

Two different jobs, often confused. A plain-English guide to when you need locating, when you need to expose, and when a job calls for both.

"Locating" and "potholing" get used interchangeably, but they're two different jobs. Knowing which you need — or whether you need both — saves time and money, and keeps your dig safe.

Cable & pipe location: find and mark

Cable and pipe location uses electromagnetic and ground-penetrating radar equipment to detect underground services from the surface, then marks their position and depth on the ground. It's non-invasive, fast, and the right first step on almost any site — giving your crew a clear picture before a shovel goes in.

Hydro excavation: expose and confirm

Hydro excavation uses high-pressure water and vacuum to safely dig down and physically expose a service without damaging it. You'd use it when you need to confirm exact depth and position — "potholing" or "daylighting" — or to dig safely around assets you can't risk striking.

When you need both

On higher-risk jobs the two work together: locate and mark everything first, then pothole the critical points to confirm them before the main excavation. That combination is what lets contractors trench through congested ground with confidence.
