concrete scanning

Deciding to scan concrete for your project was a smart decision for many reasons. It saves you time by knowing where to exactly cut, drill, or core. It saves money by preventing damages. And, most importantly, it keeps your project safe. Now that you want to move forward with our scanning services, here is what you should expect.

One of our expertly trained GPR analysts will arrive at the jobsite. Before they start scanning, they will meet with you to discuss the areas that you want scanned. You would need to provide a layout for the analyst to scan.

After this, the analyst is ready to scan. GPR (Ground Penetrating Radar) is safe to use during regular business hours. This means that any trades on the jobsite can continue with their job while the scanning takes place.

The analyst might use different types of equipment depending on the job itself. Our analysts carry the GSSI Mini XT. This equipment is ideal for locating rebar, conduits, post-tension cables, voids, and real time determination of concrete slab thickness. They also use the GSSI 2000 MHz palm antenna. This equipment works in small spaces, approximately 2” from the wall. In addition to the GPR equipment used, all analysts are also equipped with an RD 7100 unit. This unit is ideal for locating live conduits within walls, slabs, or ceilings.

While the scan takes place, the data shows up in real time. Our analysts can interpret the data and from there he/she can mark any objects directly on the concrete surface with tape, chalk, keel, or markers (as pictured above). Then, the analyst would communicate their findings with you.

Sometimes, the proposed layouts are clear and ready for coring or drilling. Some other times, the analyst finds post tension cable, rebar, or other objects in the area where the coring or drilling is proposed. If this is the case for your project, you can propose a second layout location. The analyst will then proceed to scan that area to make sure that it is clear and safe.

After the scanning, a summarized written field report of the findings will be provided you. With this piece of information, in addition to your field markings, you can make decisions as to where to cut, core, or drill. Additional electronic reports are also available upon request, including pictures and 3D scans. These reports take additional time and will be completed off-site and will be emailed to you.
