Using non-destructive diagnostic methods is currently important not only with regard to preserving existing structures but also with regard to sustainable development, which is getting more and more to the forefront of attention. This paper deals with defectoscopy of a reinforced concrete column made with artificially created defects (during concreting, the column was in some places filled with concrete with lower compressive strength and in these places it was not compacted very well) corresponding to the defects in real structures. Modern diagnostic methods enable detailed determination of the properties of structures and detection of their critical points. A method which appears to be very promising in detecting defects and failures is the ultrasonic method. It enables monitoring the development of failures at different levels of loading. Besides that, permanent deformation will also be monitored during the loading using a strain gauge. Additional measurements were performed to detect permanent damage, then the results were compared.
