GPRS Provides Concrete Scanning for Police Department in Chicago, Illinois
GPRS was contacted by a local police department to scan for a possible missing person. The case had been cold for almost 20 years! Since GPR has advanced so much since that time, the police department decided to contact GPRS for a volunteer job. Yep! You heard it right; GPRS voluntarily assisted the detectives from this police firm at no cost. GPRS plays an active role in investigating and is happy to help the community when provided the opportunity.
GPRS scanned the entire basement level of a home with two different GPR antennas. During the scans there was one area that looked different from the rest. Almost as if someone had been buried there…
While GPR cannot fully determine if a body is present, it’s sure exciting to see an anomaly that could be the possibility of a body. A hope for justice. The reaction from this anomaly can be seen further on in this article. The anomaly can also be a change in subgrade, void, prior excavation, or other unknown. Further investigation by the police firm involved would be necessary.
“Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less.” (www.gprsinc.com)
The GSSI radio waves are safe for workplaces so there is no need for any stop in work for floors below or around the scan areas. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete using our transmitter box which sends out a frequency via induction or conduction with an exposed or known surface utility line.

“GPRS deploys the best equipment operated by skilled project managers who know how solve your subsurface locating issue. Since our inception, GPRS has completed hundreds of thousands of projects in North America. Our accuracy rate on these projects? Over 99%.” (www.gprsinc.com)
GPRS technicians are commonly called for wide array of locating, such as concrete scanning for rebar, mesh, conduits, radiant tube heating, post tension cables, and any other utility that may be buried. We also scan for private and public utility locates, underground voids or vaults, footings, buried foundations, and Underground Storage Tanks (UST’s). All these tasks are all done in a safe, time efficient, non-destructive manner.
Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans.
At GPRS, safety is one our #1 priority. When saw cutting, digging, or drilling the last thing you, or our technicians, want is to run into any problems. While you may think that there is nothing buried in the concrete or ground, better think again… There is an unfortunate number of people that call because they were proven wrong. The price of one of our technicians is well worth it compared to the costs of repairing a mishap later on.
