Ground Penetrating Radar Utilized to Locate Reinforcing Steel in CMU Elevator Shaft in Corvallis, OR

A construction company needed to confirm what reinforcment was present in an elevator shaft of a large apartment complex. There was concern that no reinfrocing steel was used to build the CMU wall. Prior to beginning the inspection process, the company contacted Ground Penetrating Radar Systems of Portland to scan the elevator shaft to locate any rebar present.

GPRS used a 1600 mhz antenna for the project that allowed for precise locating of the reinforcement. GPRS marked the reinforcing steel locations directly on the walls using black permanent marker, as well as providing a detailed written report of the findings. The company was then able to proceed with confidence in knowing that the elevator shaft was properly constructed and supported.
