Ground Penetrating Radar Systems, Inc. was recently contacted to clear numerous anchor locations on the top deck of a parking garage located in Grapevine, TX. The contractors on site were tasked with installing numerous anchor plates throughout the top deck to install permanent barricades and other features, and needed to confirm that post tension cables or other anomalies would not be hit. As other work was being performed in the vicinity, the contactor needed to confirm all locations in a very timely manner and ensure worker safety.
Gasten Schoonover with Ground Penetrating Radar Systems, Inc.,was contracted to scan each anchor location and was able to clear 100 plate mounting locations in a single day. GPRS was able to provide much needed information to move their project along at an expedited pace. Gasten Schoonover, using Ground Penetrating Radar, was able to accurately mark out all post tension cables and rebar in the area, and clear each individual plate location for mounting. By locating all post tension, Ground Penetrating Radar Systems, Inc. was able to save the project future time, money, and ensure safety on site. Due to Ground Penetrating Radar Systems, Inc.’s quick response, rapid turnaround, quality of work, and industry-leading technology, we were able to ensure no disruptions were encountered and a very quick start and finish to installing each plate.

A contractor investigating the structural components of a post tension building in Washington DC contacted Ground Penetrating Radar Systems of DC for concrete scanning. The contractor hoped to find valuable information about the reinforcing and post tension cables of the building before core drilling for anchors on the slab edge. GPRS was able to mark the depths of the reinforcing and cables accurately.
GPRS scanning assists contractors by reducing the likelihood of subsurface obstruction strikes during drilling, cutting, trenching, anchoring and other sub-surface applications. Ground Penetrating Radar Systems, using GSSI Sir-3000 technology, located the critical post tension cables in the slab which allowed contractors to avoid a possible cable strike. GPRS has used different GSSI antennas to accommodate for ceiling work or even work in tight spaces giving clients data up to 1” close to walls or objects. Information was given in real time, giving the contractor quick results with a safe place to drill in each location. This was all done in a safe, time efficient, non-destructive way.
If your company needs reinforcing or post tension mapping in the Northern Virginia, Washington D.C. Arlington, Alexandria or surrounding areas with fast response times and easy scheduling, please contact Stephen Yant at 703-851-3853 or at Stephen.Yant@GP-Radar.com.
Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an engineering firm in order to scan for post tension cables on the third level of the parking structure. The purpose of the work was to repair post tension cables throughout all the levels of the structure due to many of the cables snapping or no longer sustained the proper amount of tension. The client needed areas marked out prior to chipping through the 6” thick slab. We scanned (7) 10’x4’ areas on level E and marked all findings on the surface with spray paint. We marked all post tension cables with red paint, rebar was marked with blue paint and beams were marked with pink paint.
GPR scanning is a great tool to use for post tension cables, rebar, and conduits; it can also be used to scan for underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs projects in cities like; Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area. Please contact Alfredo Espinal at 805-729-5877 or firstname.lastname@example.org to learn more about ground penetrating radar and how GPRS can assist in your projects.

Don’t be fooled by the lofty view, Chicago was nick-named the windy city for a reason!
As winds are raging, GPRS scans tight spaces atop a 48-story building in Chicago, IL. We were able to map out rebar so the general contractor could safely drill anchors for future building plans. High or low, GPRS is here to help you on any subsurface locating you need to finish your project safely and timely. Don’t hesitate to call your nearest GPRS technician today!
Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.
One of our goals at GPRS is to keep all projects on-budget and on-schedule.
GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.
Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. 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 via induction or conduction with an exposed or known surface utility line.
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. (gp-radar.com)

As a Project Manager with Ground Penetrating Radar Systems, every once in a while, you’ll find yourself scanning through an endless field, under a cloudless sky, before a backdrop of the Oquirrh Mountains, all while focusing on a scrolling Radargram–basically a dream job.
You’re confident that there’s nothing in this field, and your site contact is confident that there’s nothing in this field, but your site contact’s customer has the policy to scan the ground before ANY penetrating of the ground (even if they’re just skimming off the top couple of feet to collect fill dirt). So you scan…and scan…and scan…and scan…then you STOP.
At times like this, the value of extensive training, attention to detail, and diligence becomes evident. Had the old drainage line (marked in red, per the customer’s request, for contrast purposes) that I found with my radar been found with an excavator’s scoop, that would have constituted a Stop Work Event, causing delays, expenses, and frustration.
Nothing that travels around in a GPRS truck has more money and attention invested in it than the Project Manager in the driver’s seat. Our customers depend on not only our impressive suite of tools, our network of experienced radar technicians that covers all of the US and Canada, or our exemplary response time. But also, unknowingly, they depend on the intense, unrelenting, and unapologetically maniacal emphasis we place on problem-solving, attention to detail, and safety.
To each his own, but if you found yourself nodding your head while reading this article, then your company probably suffers from (read: “prospers because of“) the same maniacal adherence to good values. If that’s the case, then we should consider doing some business together. You will be joining a long and growing list of customers who can’t get enough of our “obsessive enthusiasm” for getting their job done right and right away.
Give your local GPRS Guru a shout.
