“Träume brauchen Sicherheit” (“Dreams Need Security”) was once the advertising claim of a big German insurance company appealing to one of the most fundamental human needs. When it comes to security, people clearly prefer building with concrete. In a joint project, Tenwinkel GmbH & Co. KG and IAB Weimar gGmbH successfully transferred and commercialized the results of their research on a mobile vehicle barrier BLOCKMAXX, made from heavyweight concrete.

“Dreams Need Security” was once the advertising claim of a big German insurance company appealing to one of the most fundamental human needs. When it comes to security, people clearly prefer building with concrete, which is a straightforward, no-frills material that easily resists exceedingly high loads while providing a high degree of flexibility and structural stability. In a joint project, Tenwinkel GmbH & Co. KG and IAB Weimar gGmbH successfully transferred and commercialized the results of their research on a mobile vehicle barrier BLOCKMAXX made from heavyweight concrete.
