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.

Whenever you can visually see concrete settling inside a building, the chances of voids could be present below the concrete floor. It’s extremely important to know the extent of the possible voids prior to conducting any repairs. The more information you have the better the situation can be assessed.
A General Contractor had a situation inside a business in Troy MI where there were visual cracks & settling of the concrete floor in spots throughout the building space. The building was built in the same location where a former house used to be. It was unknown as to what could have been possibly left underground that could cause the building to settle. Ground Penetrating Radar Systems of Michigan was contacted by the General Contractor at two separate times to check for potential voids beneath the concrete surface. During the first mobilization by GPRS, they located numerous voids throughout the building. After the General Contractor dug those areas up, they wanted more information on the extent of the voids. GPRS mobilized back to the site a few months later to scan other areas of the building. More possible voids were located during the concrete investigation. The General Contractor transferred the new information onto existing prints so they could come up with a game plan on how to repair the damage.

Prior to excavating or drilling outside, it’s helpful to have information on the sub-surface utilities that might be within the construction area. During any sub-surface exploration it’s imperative not to compromise any of the underground utilities. Having the private utilities marked will help the process continue on more smoothly.
A general contractor was asked to install a security fence around the helipad outside at the university hospital in Ann Arbor, MI. Prior to digging the post holes for the fence the contractor needed to have the areas investigated for possible underground utilities that could be in the proposed fence line. It was essential there weren’t any utilities compromised throughout the process especially near the helicopter pad. Ground Penetrating Radar Systems of Ann Arbor, MI was contacted to investigate the areas surrounding the helipad to make sure any utilities were identified prior to digging the holes for the security fence. GPRS utilized a radio detection device in the surrounding areas of the helipad where there was uneven and sloped ground to identify any utilities. Any utilities located were marked/flagged directly on the surface and then communicated to the general contractor. GPRS also provided a sketch of where the utilities were passing through in the event the flags were removed prior to the digging process. Knowing where the utilities were allowed the contractor to continue with confidence on the path of the security fence.

On October 28th, 2014 Ground Penetrating Radar Systems (GPRS) was requested on site to complete a Ground Penetrating Radar (GPR) survey. The purpose of this survey was to locate post tension cables in the elevated slab prior to anchoring in the slab. Both the uniform cables and banded cables were marked on the surface with spray paint. The customer was then able to proceed to layout the CMU walls, and rebar embedments.
We used a GSSI (Geophysical Survey Systems, Inc) Ground Penetrating Radar Unit with one specific antenna. The antenna used on this project was a 1600MHz antenna which was used to locate post tension cables in the slab.

On October 30th, 2014, Ground Penetrating Radar Systems (GPRS) was requested on site at Carowinds Amusement Park to perform a Ground Penetrating Radar (GPR) survey. The purpose of the scanning was to locate reinforcement in the new piers and footings that are being put in place for a new rollercoaster that is going in for 2015. The purpose was to locate the reinforcement prior to anchoring into the piers.

GPRS was contacted by George Allen Construction of Mokena, IL to locate underground utilities at a BNSF railway yard in Chicago. The customer was planning on excavating prior to the construction of a new building. The technician on site, Brian Cox, used GPR to locate and mark out underground utilities. The customer could then use this information when they excavate to prevent costly damages to existing utilities.
