GPRS Scans in Chicago, IL

GPRS Reinforcement Concrete Scan – Chicago, IL

“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.” (

A Chicago contractor needed to locate any reinforcement or other anomalies inside of the concrete slab at one of their project sites in the downtown area. They wanted to core through the concrete slab so they could run new electric through to the main floor from the electrical room directly below. They wanted to do this without hitting any crucial reinforcement or conduits that could be inside or underneath the slab, as this could shut down power to nearby rooms or ruin the integrity of the floor. The contractor hired Ground Penetrating Radar Systems (GPRS) to come in and mark out the reinforcement and any other anomalies in the column. The scope of the project consisted of scanning 5 varying sized locations around the room.

Using the SIR-3000 we were able to discover that the floor consisted of hollow cores with pre-tension in between the hollow points. We were able to mark out utilities to find the safest areas to drill through, the hollow points, to keep them off of the pre-tension cables. Thanks to our service the contractor was able to core into clear spots and avoid hitting the reinforcement and conduits inside and under the concrete slab.

Our state of the art GSSI GPR equipment can send signals into concrete that send data back in real time. The signals are safe for workplaces so there is no need for stoppage in work for floors below or around scan areas. The specific equipment that was utilized for this job was the GSSI 1600 MHz GPR Antenna. Using the antenna, we are able to scan concrete up to 14” thick, and see anomalies that larger antennas would miss. 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.

GPRS technicians are commonly called to scan for reinforcement such as rebar, mesh, and post tension cables. We also scan for conduits and radiant heat tubes as well.

At GPRS safety is one our #1 priority. When saw cutting or drilling the last thing you or our technicians want is to hit a surprise conduit in the slab. While you may think that there is nothing in the slab, there are an unfortunate number of clients that call because they were proven wrong. The affordable price of one of our technicians is well worth the price compared to the expensive cost of repairing a mishap later on.
