The Amtliche Prüfstelle für Baustoffe (material testing authority) is one of a few laboratories licensed for external supervision of sandwich panels in Germany and it is an important service provider for the industry as well. We permanently carry out tests for quality control on a variety of products – concrete, steel, synthetic materials, sandwich panels, etcetera. Especially in the area of sandwich technology the department of civil engineering at the University of Applied Sciences Mainz has an extraordinary reputation in the focal point of constructional engineering.

The Amtliche Prüfstelle für Baustoffe closely co-operates with the Institute of Innovative StructuresiS-mainz (formerly Institut für Sandwichtechnik - Mainz).
