What We Do
Potholing — also called utility daylighting — is the process of using hydrovac excavation to expose a buried utility at a specific point so its exact depth and position can be confirmed before mechanical digging begins. It's required by BC One Call guidelines when working within the tolerance zone of a locate, and is standard practice on any project where a utility strike would be dangerous or costly. UndergroundPower uses company-owned hydrovac trucks to perform potholing and daylighting quickly and precisely — no broker, no subcontractor, and a crew that runs this equipment every day.

Frequently Asked Questions
What is potholing and when is it required?
Potholing (also called daylighting) uses hydrovac to expose a buried utility at a specific point to confirm its exact depth and location before mechanical digging begins. BC One Call guidelines require it when working within the tolerance zone of a locate — typically within 1 metre of a marked utility.
What utilities can be potholed?
Any buried utility — electrical, gas, water, sewer, telecom, and fibre. Potholing is especially critical near high-pressure gas lines and live electrical services where a mechanical strike would be dangerous.
How many potholes can you complete in a day?
It depends on soil conditions, depth, and site access, but a typical day allows for 10–20 potholes at standard depths. We can discuss your project scope and provide a realistic timeline before mobilizing.
Do you handle BC One Call locates?
We coordinate with BC One Call as part of every job. Locates must be in place before any ground disturbance. We work within the locate window and follow safe dig procedures on every site.
Can you combine potholing with trench or conduit work?
Yes — because we do both hydrovac and underground electrical and conduit work, we can pothole to confirm utility depths, then proceed with trench excavation or conduit installation in the same visit. One crew, one mobilization.
