Hydro Excavation

Daylighting / Potholing

Expose Buried Utilities Before Crews Cut, Bore, or Trench

As part of hydro excavation, daylighting and potholing help contractors confirm utility depth, alignment, and field conditions before high-risk work begins.

Hydro excavation method

Verify the line before the heavy work starts

Daylighting exposes a buried utility so your crew can see it: position, depth, size, and condition. Potholing does the same at spot locations along a bore path or trench line.

Surface marks tell you roughly where a line runs. An open exposure tells you exactly. That difference protects your schedule, your equipment, and the people in the trench.

When to daylight

Before directional bores, trench crossings, tie-ins, repairs near live lines, and any dig where the locate ticket leaves doubt.

What gets exposed

Gas, water, sewer, storm, electric, telecom, and fiber. One pothole or a full series along the bore path.

What you get

Visual confirmation of depth and alignment, exposure photos, and a hole sized to the next crew's work.

Same excavation family

Trenching, slot trenching, and debris removal are other tasks within hydro excavation.

Common questions

How is potholing priced?

Single exposures are usually priced per pothole, with an hourly fallback for hard ground. A series along a bore path gets a project quote.

How many exposures can a crew finish in a day?

Ground and depth decide it. In typical soil a crew works through eight to twelve potholes a day.

Do you backfill the holes?

Yes. Holes get backfilled and compacted to your spec, or plated when the exposure needs to stay open.

What should be ready when the truck arrives?
  • Locate tickets called in and marks on the ground
  • Bore path or exposure points staked
  • Truck access within hose reach of each point
  • A site contact for the crew walk-in
