This project has studied if RFID technology can be used to measure the thickness of shotcrete applied to walls, such as in tunnel construction. An RFID tag can be placed on the wall before the shotcrete is applied. When the RFID reader contacts the tag through the shotcrete the loss in signal strength can be measured. The goal was to analyse how the loss in signal strength through the medium related to the thickness of the shotcrete. Several tests with RFID tags cast into shotcrete has been performed. The results show that shotcrete is far too inhomogeneous for the measurements to convey meaningful information about the thickness. RFID is not recommended to be used for measuring shotcrete thickness.
