Yes. Unlike electromagnetic methods such as those employed by GPR and cover meters, which do not work on steel fibre reinforced concrete, ultrasonic pulse echo is well suited for measuring on this material. It has been successfully used for detecting voids, detecting cover depth to rebars and pipes and also for determining the thickness of shotcrete layers.
