Ground penetrating radar (GPR) has emerged as an alternative way of non-destructive concrete testing for locating post tension cables, steel reinforcement, and conduits, making it safer to drill, cut or core concrete.
The thickness of concrete slab may also be detected. Similar to pachometers, GPR scanning doesn't have those safety concerns of radiographic inspection and it can be performed from only one side of the concrete. But compared to pachometers, GPR can detect deeper objects and also non-metallic objects such as PVC conduits. GPR may also be used to detect voids within and under concrete slabs.
Utility Survey Corp. uses a variety of high resolution antennas that allow the operator to balance between the resolution and the penetration depth. We only use state of art GPR equipment which is fully portable and runs entirely on batteries without the requirement for long extension cables or on-site power, making a safer work environment.
