It is shown that for the full and effective examination of finished concrete piles of important objects two diagnostic methods should be used together: vibro-diagnostics on the basis of the echo method and acoustic logging. We designed and constructed an experimental model of system for examination of pile foundations which implements methods of acoustic logging and vibro-diagnostics and is built on the basis of piezoelectric elements of a unified design and advanced electronic components. Its experimental tests have been performed at building sites in Kiev city with usage of special test equipment.
