Concrete Scanning before Coring or Saw-cutting

Ground Penetrating Radar Systems of Arkansas received a call from a general contractor working in Little Rock with concerns about what may be in the slab prior to core drilling in a bank. He asked what type of results he could expect when scanning concrete elevated slabs prior to core drilling.

 GPR can locate conduits, tension cable, rebar, slab boxes, voids and more, which allows for incident-free drilling or sawing. Knowing where to cut and where not to can help maintain the integrity of a project, as well as prevent costly or even dangerous incidents.

While onsite, site GPR was able to locate post tension cables in all 10 of the contractor’s coring locations. We cleared an area in each location for the contractor to core so that there would be no issues or danger involved when core drilling.

We also let him know about our outdoor utility locating services. Excavating outdoors is often quite a challenge with the huge amount of infrastructure underground, including electrical lines, pipes, gas lines and tanks that are in the ground. The “811” service is in place to locate public utilities, however, they do not locate private utilities, which are just as dangerous.

Unfortunately, we all too often receive calls about clients needing our services after they cut or damaged conduits or tension cables, but it is our mission to provide these services prior to the incident, so it is encouraged to make it common practice to include concrete mapping or locating (concrete or utility) in your quotes and bids.

When you are cutting or coring concrete, it is important to have it scanned. Utilizing GPR on your project can help reduce injury, reduce lost productivity, and maintain that incident-free professionalism that you demand. Our safety culture is comprehensive, ongoing, and guides the manner in which we all do our jobs.
