Ground Penetrating Radar Systems

Since September of 2001, GPRS has performed expert private utility locating services on tens of thousands of job sites nationwide.

Our team of project managers, radar experts, and service technicians provide a full suite of state-of-the-art utility locating services, designed to help your team avoid accidental underground strikes that can result in costly repairs or severe injury.

Accidental underground utility strikes are one of the most common injuries that excavation and construction teams face, and yet they are easily avoidable. By employing an experienced professional utility locating contractor like the team at GPRS, you can get a complete and accurate location of all of the subsurface utilities. We provide detailed site maps of the electrical, gas, sewer, water and data utilities, so your team can avoid subsurface hazards before they dig.

GPRS provides a more complete and more accurate evaluation of job sites, locating both subsurface public and private utility lines. We utilize industry leading technology, and are constantly pursuing training and educational opportunities on the latest tools and techniques. GPRS takes pride in providing industry leading utility locating services, and with project managers in every major metro area across the country, can often be to your job site in hours.

3 Key Issues to Consider


The biggest reason to employ a utility locating service like GPRS on your project is to help keep your team safe from the result of an accidental utility strike. Severe injury, or death, can occur if they make contact with a live electrical line or high pressure gas line. The only way to be 100% sure you won’t strike electrical, gas, sewer, water and data utilities is to get a complete and accurate utility locating map of the job site before you start, and the only way you can get that is by hiring a utility locating contractor like GPRS.


The bread and butter of any good construction company is repeat business from happy customers. With multiple technologies GPRS uses, we can scan for buried private utility lines, including electrical, gas, sewer, water and data lines. There is no reason to risk losing good customers over ignoring a fundamental project checklist item like a subsurface utility scan. Call BEFORE you dig!


If you do accidentally cut a post tension cable or damage a gas line, you will be required to pay for the repairs. Worst of all, the site may be deemed unsafe, which could cause costly delays in project completion. It may only be a day or two, but even a single hour of downtime will begin costing you money unnecessarily. The possibility of compounding scheduling delays will occur since certain tasks have to be completed before others can take place. Keep your project on time and on budget with the utility locating services of GPRS.

Why Should You Utilize GPRS?

Unlike companies that offer multiple services, at Ground Penetrating Radar Systems we focus on a single task. We specialize in utility locating and concrete scanning, and our experience and expertise in the industry is second to none.

We built our own training center where every GPRS project manager is required to complete an extensive education program. We make them train on a variety of equipment, in a number of different settings and surfaces, before they can perform field services on your job site. Our staff includes a full-time training and safety director to make sure all our project managers are skilled in operating our equipment with high levels of competence and confidence, while always being conscientious about performing duties safely and accurately.

GPRS was one of the first utility locating contractors in the country to focus exclusively on concrete scanning and utility locating services. Though we primarily use ground penetrating radar, we’ve broadened our techniques to include thermal scanning and imaging, electromagnetic induction, and CCTV sewer camera systems for direct scanning of subsurface utility lines.

Since GPRS started in September, 2001, we have built a nationwide network, with staff permanently based in over 50 cities and metro areas throughout the United States. We have worked on some of the largest and most significant construction projects in the country, and take pride in offering services that keep crews safe and safe our clients time and money.
