The Smarter Way to Locate the Unknown

What GPR Does and Why It Matters


GPR is a non-invasive scanning method that uses radar signals to detect underground anomalies — ideal for non-metallic utilities like water, sewer, and leach lines. It’s the perfect choice when standard locating methods fall short.

Our experienced technicians interpret every scan precisely, even in challenging Central Coast soils, so you can plan and dig with confidence.

GPR Insights

Ground Penetrating Radar – Your Questions Answered


  • What can GPR detect underground?

    GPR can identify non-metallic utilities, voids, trenches, and anomalies beneath the surface—great for locating water or sewer lines that don’t carry current.

  • How deep can GPR scan?

    Depth depends on soil conditions.

  • When should I request a GPR scan?

    Before digging, trenching, or saw-cutting, especially when dealing with unknown or untraceable utilities.

  • Does GPR replace standard utility locating?

    Not exactly. It complements standard locating methods to give you a more complete picture of what’s underground.

  • Will I receive a report or visual data?

    Yes. We provide on-site markings and a summary of findings—photos are available upon request.
