Ground Penetrating Radar (GPR)
See beneath the surface without digging. Locate utilities, pipes, voids, and moisture with advanced GPR technology.
How GPR Works
Ground Penetrating Radar sends electromagnetic pulses into the ground and measures the reflections from buried objects and material boundaries. Different materials reflect signals differently, creating a detailed subsurface image.
- Non-Destructive: No digging, drilling, or damage required
- Real-Time Imaging: See results immediately on screen
- Depth Information: Know how deep objects are buried
- Multiple Frequencies: Different antennas for various depths
What We Locate
- Underground utilities and pipes
- Rebar and post-tension cables
- Voids and sinkholes
- Underground storage tanks
- Moisture and water intrusion
- Buried foundations and structures
GPR Applications
Concrete Scanning
Locate rebar, conduits, and post-tension cables before cutting or drilling into concrete slabs and walls.
Utility Locating
Find water, sewer, gas, electrical, and telecom lines before excavation to prevent costly utility strikes.
Void Detection
Identify voids, sinkholes, and areas of soil erosion beneath slabs, roads, and foundations.
Frequently Asked Questions
What can GPR detect?
GPR can detect buried utilities, pipes, rebar, post-tension cables, voids, moisture pockets, underground storage tanks, conduits, and changes in soil composition. It works through concrete, asphalt, soil, and other materials.
How deep can GPR see?
Depth penetration varies by soil conditions and antenna frequency. In ideal conditions, we can see 10-15 feet deep in soil. For concrete scanning, we typically achieve 12-18 inches of penetration.
Is GPR safe to use?
Yes, GPR is completely safe. It uses low-power radio waves similar to a cell phone, with no radiation or hazardous emissions. It can be used safely around people, electronics, and sensitive equipment.
When should I use GPR vs. other methods?
GPR is best when you need to locate utilities before excavation, scan concrete before drilling, find voids or moisture under slabs, or map underground features without digging. We often combine GPR with other detection methods for comprehensive results.
Need GPR Scanning?
Know what's beneath the surface before you dig or drill. Our GPR services prevent costly utility strikes and damage.
