What Is Underground Utility Locating?

Underground utility locating is the professional process of identifying and mapping buried infrastructure before any excavation, drilling, or construction begins. It involves the use of specialized geophysical equipment to detect various types of pipes, cables, and storage tanks that are hidden beneath the earth's surface.

By providing an accurate "view" of what lies beneath, we enable project teams to design and build with confidence, avoiding costly delays and safety hazards associated with accidental utility strikes.

Ground Penetrating Radar (GPR) for Utility Detection

Ground Penetrating Radar (GPR) is the gold standard for non-destructive utility detection. Unlike traditional methods that require a conductive signal, GPR can detect both metallic and non-metallic objects (such as PVC pipes or concrete conduits).

This technology is essential when site records are incomplete, outdated, or inaccurate. We use multi-frequency GPR systems to provide high-resolution data at varying depths, ensuring no utility is left unmapped.

Why Utility Locating Is Important Before Excavation

Safety & Injury Prevention

Striking high-pressure gas lines or high-voltage electric cables can cause catastrophic injuries or fatalities on site.

Service Interruptions

Damaging fiber optic or water mains can disconnect entire neighborhoods, leading to massive liability and repair costs.

Project Budget & Timeline

Preventing a single strike saves thousands in emergency repairs and avoids weeks of project downtime.

Frequently Asked Questions

How deep can Ground Penetrating Radar (GPR) see? expand_more
Typically, GPR can detect utilities up to 10-15 feet deep depending on soil conditions. Clay-heavy or saturated soils may reduce penetration depth, while sandy or dry soils allow for deeper imaging.
Can GPR detect plastic or PVC pipes? expand_more
Yes, one of the primary advantages of GPR is its ability to detect non-metallic utilities like PVC, fiber optic, and concrete pipes that traditional electromagnetic locators cannot find without a tracer wire.
What is the difference between private and public utility locating? expand_more
Public locating services (like 811) typically only mark utilities up to the service meter or property line. Private locators like Global GPR mark everything beyond that point, including internal distribution lines, parking lot lighting, and specialized facility infrastructure.
How soon can you be on my job site? expand_more
We pride ourselves on rapid mobilization. In most regions, we can have a technician on-site within 24-48 hours. For emergency needs, please call our direct hotline.
