GPR Used To Scan Concrete for Compressive Strength Testing
A general 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.
