Concrete Imaging Technology Utilized to Map Rebar Within an Elevated Slab Prior to Core Drilling - Cambridge, MA

Concrete Imaging Project - Cambridge, MAAn engineer needed to core one 4” hole in order to run drainage lines up to the new bathtub in a renovation project. Prior to drilling, the engineer needed to be sure that no reinforcing was compromised during coring. In order to miss all of the reinforcing, the engineer had to have all of the reinforcing within the elevated slab accurately mapped out. In order to get the accurate results that he required, the contractor contacted Ground Penetrating Radar Systems of New England to scan the concrete to locate a clear path for the core location. GPRS used a High Resolution 1600MHz Antenna for the project that is able to scan concrete up to 15” in thickness with an incredible accuracy of +/-1/4” on the location and depth of the anomaly. GPRS marked the reinforcing on the slab and created a report so that the engineer had verification that he had taken every step necessary in order to ensure that no conduits were hit during the drilling process.
