Utility Locating & GPR

Private Utility Locating

Electromagnetic and GPR locating of privately owned underground utilities — the lines one-call services don't mark — before you dig.

Watch Us Work

Marked. Mapped. Documented.

This is what a PCI locate looks like on the ground — methodical passes with GPR and electromagnetic gear until the whole picture is painted, whether that's a downtown lot or a coastal townsite at the end of a logging road.

Public one-call services (BC 1 Call, Utility Safety Partners, Yukon locate services) generally mark buried utilities only up to the utility provider's demarcation point — the meter, the property line, or the service entrance. Beyond that point, privately owned lines like site electrical, gas runs to buildings and tanks, water and sewer services, irrigation, communications and process piping are the owner's responsibility. Those are the lines PCI Surveys finds.

Our locators use Vivax-Metrotech electromagnetic equipment, ground-penetrating radar, sondes and sewer cameras to trace, identify and mark private underground utilities on commercial, industrial, institutional and residential properties across BC, Alberta and the Yukon — before excavation, drilling, trenching or any ground disturbance.

Common Questions

Utility Locating FAQs

What is Underground Utility Locating?

Underground Utility Locating is a critical process to identify and mark buried utilities like water, gas, and electricity lines before excavation to prevent damage and ensure safety.

Why is Underground Utility Locating Important Before Digging?

Locating utilities before digging prevents damage to underground lines, avoiding costly repairs and safety hazards. It’s often legally required for public safety.

How Does Underground Utility Locating Work?

The process uses specialized equipment like ground-penetrating radar to detect underground utilities. Technicians mark these locations above ground for safe excavation.

What Types of Underground Utilities Can be Detected?

Most underground utilities, including water, gas, electricity, and telecommunication lines, can be detected using modern locating technologies.

How long are locates good for?

14 days or whenever the marks have been destroyed.
