The state of the art in non-destructive testing of building structures remained on a low level for many years in comparison with its application in the areas of machine building or medicine. A major reason for that is the heterogeneous nature of reinforced concrete, the typical size of the structures and last but not least the traditional thinking of the building industry. During the last decade successful efforts had been undertaken to improve this situation. Methods had been developed to use acoustic and electromagnetic waves, temperature pattern of the surface, vibrational behaviour etc. for inspection and for quality control in the production phase. A display of recent developments in the field of ultrasound examples for practical applications will be given.
