Frequently Asked Questions

  • 1. What is underground utility locating?

    Underground utility locating identifies the position of buried services like gas, water, sewer and power lines to prevent damage, ensure safety and support compliant excavation or construction work.

  • 2. How do professionals locate underground utilities?

    Professionals use electromagnetic locators and ground-penetrating radar (GPR) to detect pipes and cables. These tools trace signals or reflections to create a clear map of what’s beneath the surface.

  • 3. Why is utility locating important before digging?

    Utility locating helps prevent hitting buried lines, which can cause serious injury, costly repairs, legal issues and service outages. It’s essential before any excavation or ground penetration project.

  • 4. Can utility locators find non-metallic pipes?

    Yes, non-metallic pipes like PVC can be located using ground-penetrating radar or tracer wires. These methods detect changes in subsurface materials or follow inserted conductors to find plastic lines.
