Abstract: The current assessment of the material condition in hydraulic engineering structures is mainly based on visual survey and knocking on the surface of the structure in apparently damaged areas with subsequent extraction of drilling cores. The drilling cores are evaluated visually and also tested in the laboratory concerning their material properties with conventional methods (e.g. mechanical testing and chemical analysis). The results of these selective investigations are related to the entire structure. In this paper new possibilities are highlighted using innovative testing methods for the non-destructive assessment of the material condition in hydraulic engineering structures. For example the combined application of radar measurements and ultrasonic measurements may provide much more information about the structural state than the current assessment methods. Furthermore new perspectives for laboratory damage analysis are presented which are issued by the application of 3D X-ray tomography and micro X-ray fluorescence analysis.
