Advanced Data Acquisition:

Ground Penetrating Radar

Ground Penetrating Radar (GPR) offers a non-invasive method for detecting underground utilities, structures, and anomalies. We provide GPR services as a tool in your data collection and verification process providing precise, real-time data to help you avoid costly surprises during your project.

Service Benefits:

  • Non-Destructive: Analyze subsurface features without excavation.

  • High Accuracy: Detect utilities, rebar, voids, and more with precision.

  • Time & Cost Efficiency: Fast results reduce delays and avoid unplanned costs.

  • Versatile Applications: GPR supports utility locating and structural analysis needs.

  • Increase Safety: Build redundancy and reduce the chance of line strikes

What You Can Expect

We conduct GPR scans to detect utilities, voids, or structural issues, providing real-time data visualization. Our team generates actionable reports to integrate with your project plans, ensuring minimal risk and enhanced accuracy.

Highlights of Design Projects We Support:

Utility Detection: Locates pipes, cables, and other utilities underground to prevent damage during excavation.

Concrete Scanning: Identifies rebar, conduits, and voids in concrete structures before cutting or coring.

Environmental Studies: Detects subsurface contaminants, underground storage tanks, and environmental hazards.

Geological Surveys: Measures soil layers, water tables, bedrock depth, and rock formations to aid in construction planning and site analysis.

Subsurface Utility Engineering (SUE) Surveys: Stay compliant with your SUE surveys by providing level B, designating services. We also provide level A verification test hole services.

Frequently Asked Questions

  • GPR sends radar pulses into the ground, recording the strength and time of reflections directed back up caused from different materials underground.

    Reflections are produced whenever the energy pulse meets a material with different electrical conduction properties or dielectric permittivity and bounces back. The strength of the reflection is determined by the contrast in the dielectric and conductivities of the two materials. This can tell us what material the object is made out of, and how deep it is under the surface.

    Once the reflections come back up towards the surface, the antenna captures the time it took to travel and its strength and records it in the visual model on the screen.

  • GPR can locate utilities like pipes and cables, as well as voids, rebar in concrete, and geological features. It is also effective for detecting non-metallic objects.

  • GPR penetration depth varies based on soil conditions and the frequency of the antenna, typically reaching depths between a few centimeters and 30 meters.

  • Survey times depend on project size and complexity but usually range from a few hours to several days. We offer expedited reporting for urgent projects.
