CTA’s Environmental team has planned and implemented numerous detailed investigations using our in-house Ground Penetrating Radar (GPR) system. The GPR System detects and maps internal components in concrete structures, including: reinforcement bars, tension tendons, electrical conduit, plastic piping, and radiant heating tubes. These services assist CTA’s clients in providing clearances prior to drilling holes or setting anchor bolts, and in determining approximate size, location and orientation of unknown reinforcements.
