How GPR Works
Ground Penetrating Radar (GPR) is a non-destructive geophysical method that uses radio waves to capture images below the surface.
Signal Emission
GPR antennas transmit high-frequency electromagnetic (radio) waves into the ground or concrete.
Subsurface Reflection
When waves hit buried objects or boundary layers, they reflect back to a receiving antenna.
Data Visualization
The variations in reflected signals are processed into a digital profile, revealing the location and depth of targets.
Industry Focus
Providing precise data for diverse professional fields across the globe.

Frequently Asked Questions
What can GPR actually see? expand_more
GPR can detect metallic and non-metallic objects including rebar, tension cables, plastic pipes, conduits, voids, and even archeological artifacts in soil or concrete.
How deep can you scan? expand_more
Concrete scanning typically reaches up to 24 inches. In soil, depth depends on conductivity; we can often see 10-15 feet deep, and in ideal dry conditions, up to 30 feet or more with specialized antennas.
Is GPR safe for our workers and the public? expand_more
Absolutely. Unlike X-ray imaging, GPR emits no harmful radiation. It is completely safe to use in active hospitals, schools, and crowded job sites without clearing the area.
How fast can I get the results? expand_more
We provide immediate results on-site. Field markings are made in real-time. Formal digital reports with 3D mapping can typically be delivered within 24-48 hours after the survey is completed.
