Frequently Asked Questions

Q: I'm familiar with GPR, is this the same technology that has been around since the 1970's?
A: No. The theory of GPR remains the same, but thanks to faster computers and an explosion of research we offer state-of-the-art methods. Our surveys are performed at speeds up to 45 mph, with high resolution, and superior results. All data is analyzed with a 3D image and plotted directly onto structural drawings. This is definitely the next generation of Ground Penetrating Radar!

Q: How does GPR work?
A: The antenna sends radio waves into the ground to measure differences in electrical properties of the area. From that precise information, software and a trained operator can interpret the signal.

Q: Are there any safety concerns or interference issues?
A: Radio waves, unlike X-ray, are not considered to be harmful. All Resource International equipment is FCC compliant. In addition, several safety measures are taken during a survey to protect our crew, the equipment and other persons in the area.

Q: How deep can the radar survey penetrate?
A: The radar signal depth is dependent on the type of material and selection of antenna. Under good conditions a radar survey can hear to a depth of 50 meters.

Q: What is the cost of a typical survey?
A: Survey costs are determined to meet your needs. Please contact one of our offices for a quote on our services.

Q: How quickly is a survey project completed?
A: Resource International performs a thorough GPR survey and analysis of the data received. Once is it scheduled, a typical GPR survey consists of four to eight hours followed by two to three days of analysis.

Q: What surveys has Resource International recently performed?
A: See our recent projects page!
