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.

Ground Penetrating Radar Systems, Inc. – GPRS – of Wisconsin was contacted by a trailer manufacturing plant to locate electrical running through areas inside the plant. The manufacturing plant had hit a large electrical line prior to calling GPRS, Inc. GPRS was able to locate four additional power lines in areas of which they were planning on digging prior to remodeling their new assembly line. After locating these electrical lines, we were able to determine if they did not contact GPRS, Inc. that these lines would have been cut as well.
Using our 400 MHz antenna we were able to see well into the slab and in areas where concrete was previously cut out. Ground penetrating radar 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. Please contact Ground Penetrating Radar Systems – GPRS to learn how we can assist with your project. To locate rebar, post tension cables, voids, conduits, pipes or utilities in concrete or underground please contact us today. email@example.com.

This concrete scan was conducted inside an office building in Lubbock, TX. The general contractor needed to drill several concrete cores to retrofit wiring for a renovation. Knowing that existing electrical conduits ran through the slab, it was imperative to identify them prior to drilling. David Hagenmayer with Ground Penetrating Radar Systems, Inc., was called out to scan the floor to determine if there were any existing utilities running through the proposed coring areas. David was able to verify the conduits near the proposed holes and marked them out on the surface accordingly. The contractor was then able to drill through the slab safely without damaging the existing utilities.
Ground Penetrating Radar is cost effective, non-hazardous, and provides data in real time.

A client was looking to trench approximately 300 feet long x 2 feet wide x 3 feet deep. The purpose of this trench was to install new underground conduits to feed the communication lines through. The client knew there were multiple utilities in their proposed trench line, however they did not know exactly where or what depth they were at. Since this location was an active gas station in Lancaster, PA there were more utilities than normal, as well as the underground storage tanks (UST’s) on site. The client did not want to risk hitting any of these utilities due to the cost of fixing them, as well as the risk of injury that may occur. They called Ground Penetrating Radar Systems to come out and locate all utilities and UST’s in their proposed trench line. Sam Hart, who is based out of the Harrisburg office and covers the mid-state, was able to come out and complete the job the very next day. Sam located the gas line, 2 water lines, electric lines, irrigation lines, storm drain, multiple UST’s, sewer line, and an empty conduit. Upon location, he painted and flagged the utilities with their depths.
GPRS performs GPR scanning to locate any utilities or anything sub-surface before drilling or excavating. For any projects in Central Pennsylvania, contact Sam Hart at 717-798-5721 or firstname.lastname@example.org. Ground Penetrating Radar Systems has a representative in every major city, so we are able to come out and scan as soon as you need us. It’s always best to have as much information available about anything that may subsurface before any project. It can save money as well as ensure a safer working environment. Sam has also worked in Hanover, Lebanon, State College and Palmyra.
On December 16th, 2014 Ground Penetrating Radar Systems (GPRS) was requested by an environmental firm to complete a Ground Penetrating Radar (GPR) survey. The purpose of this survey was to locate any utilities that may be present prior to completing soil borings and drilling.
We used a GSSI (Geophysical Survey Systems, Inc) Ground Penetrating Radar Unit with one specific antenna. The antenna used on this project was a 400MHz antenna which was used to help identify any utilities or anomalies that may have been present in designated areas prior to drilling.

A Pennsylvania Hospital undergoing some upgrades and renovations needed to remove a huge section of floor so that they could transport a brand new, state of the art MRI machine down into the basement to replace their old equipment. Before they could cut the floor open, the structural engineers working with the general contractor needed to decide if removing the floor might compromise the structural integrity of the building, so they contacted Ground Penetrating Radar Systems (GPRS) to perform a survey of the concrete and identify what type of reinforcing was present within the slab. Daniel Slachta, the Project Manager of Southern New Jersey and the tri state area performed scans and compiled the data. A full report was provided to the engineers, allowing an informed decision on the next course of action.

Ground Penetrating Radar Systems, Inc. was contacted by a large contractor in San Diego to locate and map out underground utilities. Ground Penetrating Radar Systems, Inc. used a 400 MHz GPR antenna to perform the survey. The findings were marked directly on the surface with color coordinated spray paint as seen in the picture above. This enabled the contractor the confidence and knowledge to continue with their trenching.
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, environmental firms, and excavators.
