Beginning with november 2021 Betontest reduces the offered services to:

• noise measurements,
• vibration monitoring and
• consulting in the area of building diagnostics.

Utilizing the ultrasonic inspection method Betontest examined the quality of the concrete filling of steel piles supporting offshore constructions in the Persian Gulf. The ultrasonic probes were positioned by divers. The evaluation of ultrasound data in terms of data quality was carried out on the supply ship immediately after the measurement. The accepted measurement data was electronically transmitted to the Betontests office in Darmstadt, Germany, and evaluated. The results were reported to the site.

Sensitive system areas such as data and control centers can be affected by vibrations in their ability to function. The risk of such vibrations arises particularly in construction activities in the nearby environment. To counteract these vibrations, it requires the determination of plant-related limits and monitoring of the vibrations. Betontest measures these and forwards the collected data to the plant operator. Exceedances of the determined threshold are reported directly via mobile phone to selected recipients.

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.
