In order to monitor the noise immissions of a building site, the main contractor decided to control the works by noise measurements. The results indicate if a noise reduction action is required. Betontest was asked to get active in that field and expanded its service offerings.

Betontest was involved with co-athourship for the preparation of the article Hans-Wolf Reinhardt: Echo-Verfahren in der zerstörungsfreien Zustandsuntersuchung von Betonbauteilen (engl: echo-methods in non-destructive methods of concrete structures)

A series of ultrasonic measurements on a tunnel lining mockup made of self-compacting concrete showed that the fluctuation of sound velocity in the material is below 3.0%.

Bundesanstalt für Straßenwesen (BASt) which is an institute of the German federal agency for road construction initiated comparative wall-thickness measurements according to RI-ZFP-TU at three blocks of tunnel Burgholz. Betontest participated by applying ultrasonic pulse-echo technique.
