Application of GPR-technology for identifying the material composition of building components

Abstract: Currently various technologies are used in order to determine the geometry of existing buildings, however there is no established technology to identify the material composition of buildings. The state-of-the-art material identification of existing buildings is conducted manually through destructive methods, which is not accurate enough and cannot be applied in the operation phase. Within this paper, ground penetrating radar (GPR) technology is applied on a real use case to determine the material composition of buildings. The state-of-the-art and high-tech GPR methods are compared regarding costs and time effort. Results show, that the GPR has great potential, but requires further optimizations.
