Ground Penetrating Radar Used To Scan Concrete For Compressive Strength Testing
A general contractor, constructing new municipal County buildings, received a concrete test report with low compressive strength results at one location in a concrete slab.
In order to conduct further testing, the lab sampling specifications require a core sample at the concrete load location that did not meet plan requirements. Per the specifications, the core sample cannot contain any rebar or welded wire mesh that may cause inaccurate compressive strength results.
The contractor asked Ground Penetrating Radar Systems to scan the slab at that load location to locate and mark any reinforcing steel. Central Florida GPRS, LLC. technician, David Abueg, scanned the concrete and provided markings on the surface. This allowed the contractor to see the locations of the welded wire mesh and choose a clear spot for the representative core sample to be cut.
