GPR Scanning to Determine Thickness of Concrete in Jones Stadium – Lubbock, TX

The stadium is undergoing a major facelift with new bleachers being installed. Prior to demolition of the existing bleachers, the customer needed to determine the thickness of the concrete to ensure the new construction would be supported sufficiently.

David Hagenmayer with Ground Penetrating Radar Systems, Inc., was called out to scan several sections of the bleachers to determine the thickness of the concrete. David was able to verify the average slab thickness in all of the scanned areas. The client was then able to take that information and incorporate it into their figures to make the appropriate modifications prior to construction.

Ground Penetrating Radar is cost effective, non-hazardous, and provides data in real time.

Ground Penetrating Radar Scan Performed at LAX – Southern California

Ground Penetrating Radar Systems, Inc. – GPRS – of California was contacted by an electric company to locate conduit and reinforcing in the slab prior to anchoring and coring for a new kiosk.

We were asked to mark all findings with blue tape and differentiate conduit from reinforcing. We scanned a total of 14 locations throughout the airport and scanned a 3’x3’ area at each location. We used our 1600 MHz antenna to locate all findings and were able to determine that there was 6” on center wire mesh over the metal decking slab.

Ground penetrating Radar mapping is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating.

Environmental Company Utilizes GPRS to Minimize the Risk of Striking a Utility – Jacksonville, FL

Ground Penetrating Radar Systems’ office of Jacksonville, Florida was contacted recently to clear soil borings on an abandoned plant site. The environmental company completing the soil testing wanted to ensure all drilling and boring locations could be completed as safely as possible and minimize the risk of striking a utility.

GPRS used ground penetrating radar to locate and map the utilities prior to any work being completed. Each location was scanned and utilities such as water lines, electrical lines, telecommunication and fiber lines and a large gas line were all located near the drilling locations. All of these utilities were mapped on site and painted on the surface to signify the location of the utility beneath the surface.

Once the client was clear on the location and depth of the utilities, work could then commence safely. The drilling company was able to drill each location safely, without disrupting any live utilities or injuring any of their employees thanks to the locate work completed by GPRS.

Concrete Imaging Technology Utilized to Scan an Elevated Slab inside a Hospital – Detroit, MI

Detroit1Typically anytime you have a need to core drill holes in older buildings, you’ll find that conduits & other obstructions are in the way of successfully performing the work without complications. It is always best to have as much information as possible to what may inhibit the drilling process. The last thing you would want is to shut down a business by drilling through electrical conduits.

A general contractor was faced with a project where they had to core drill numerous holes through an elevated slab inside a hospital in Detroit, MI. It was unknown as to what may be in the slab that could potentially cause issues during the drilling process. The general contractor also didn’t know what type of construction the elevated slabs were. They could have been metal pan deck, waffle slab, hollow core or beam slab. It was essential the contractor didn’t drill through any beams along with conduits.

Ground Penetrating Radar Systems of Detroit was contacted to scan the proposed areas to determine the paths of any obstructions prior to core drilling. GPRS was able to utilize a 1600 MHz high resolution radar antenna to investigate the locations. The technology used allowed GPRS to mark the findings directly on the slab in real time. They successfully marked the paths of numerous concrete beams & a bank of conduits passing through the proposed coring locations. Prior to leaving the site, GPRS technician communicated all of the findings to the contractor’s onsite to ensure the understanding of the markings.

Private Utility Locating Project – Carmel, IN

CarmelGround Penetrating Radar Systems’ Indianapolis office worked with a homeowner in Carmel, IN on January 30, 2015 to locate the septic system before building an addition onto their home.

GPRS marked the location of the septic tank, distribution box, and septic fingers using the GPR 400MHz antenna. The utilities were marked with paint and flags when appropriate. The project was successful and nothing was hit.

This was a very practical and common application for using GPR before building onto your home or business. The client had drawings from the builder to reference, but drawings are never as reliable as GPRS. We marked the septic system 10ft off the original drawings, preventing a possible catastrophe.

Other services we offer are: Post-Tension Cable Location, Conduit Mapping, Rebar Mapping, Void Location and more.

If GPR services are needed in Indianapolis, Evansville, South Bend, Hammond, Bloomington, Gary, Carmel, Fishers, Muncie, Lafayette, Terre Haute, Anderson, Noblesville, Elkhart, Greenwood, Mishawaka, Lawrence, Kokomo, or any others not listed call Josh Dotson at 317-504-1068 or email at josh.dotson@gp-radar.com.
