On September 17, the joint event on concrete repair took place at the Institute for Materials Testing for the first time in six years after a break due to the pandemic. Organized together with the Landesgütegemeinschaft Instandsetzung von Betonbauwerken Bremen und Niedersachsen e.V., experts from all over the region came together to find out about innovations in concrete repair and the latest regulations and specifications. The overarching focus this time was on sustainability. The tradition of demonstrations was also maintained: PCI Augsburg GmbH presented concrete repair systems in terms of application technology as part of the event.
