We use the latest ground penetrating technology to provide critical information on utilities, materials, and other potential obstructions within existing structures or underground. Fast and reliable, GPRS provides both two- and three-dimensional images of the scanned areas without delivering any radiation. All of our equipment is registered and meets all standard FCC regulations.
Utilizing GPR reduces risk and cost, promotes a safe work environment, and provides non-destructive testing by locating materials such as concrete, plastic, metal, steel, rock, soil, ice, and pavement. Our client base includes hospitals, universities, surveyors, engineers, homeowners, contractors, environmentalists,
and excavators. |

Example of locating the exact location of rebar in
concrete using Ground Penetrating Radar |

GPRS is excited to provide global positioning system (GPS) technology for use on your outdoor projects, such as environmental surveys and the detection of underground utility layouts. In conjunction with our GPR and electromagnetic induction technologies, we use a hand-held GPS device to create a comprehensive map of the underground area of your job site that then can be overlaid onto CAD documents and / or Google Earth maps. Utilizing GPS technology along with our GPR and EMI services will give you a permanent record of the physical reference points of your project area’s underground environmental / utility layout. For more information on this resource, please contact your local GPRS representative today!

To Whom it May Concern,
Let me take this opportunity to provide a exemplory recommendation for Ground Penetrating Radar Systems, Inc. and the professional service they have delivered. Turner was the General Contractor for the 2008 Democratic National Convention in Denver Colorado. We utilized GPRS to ensure safe drilling areas in over 150 locations at the Pepsi Center through very congested floor slabs. The project schedule was extremely tight and the accuracy of the information provided was remarkably very sound. GPRS was instrumental in assisting in a very successful project for the entire design / build team. Turner has since and certainly will continue to use Ground Penetrating Radar Systems, Inc. prior to cutting into existing slabs and walls.
Respectfully,
Mike Keith
Project Manager

Ground
Penetrating Radar technology provides critical
information concerning anything that lies below the surface.
This technology has been used for a variety of scanning
purposes, but it is commonly used to determine the location
of underground utilities, rebar, post-tension
cables, electrical
conduit and other impediments.
This technology
works in a fast and reliable manner. It is also
very safe, as it uses no radiation.
We are able to provide a 2
Dimensional and a 3 Dimensional image of the areas we
scan.
All
of our equipment is registered and meets all standard
FCC regulations.
