 Since 1909, Rinninger, a family-run company in the South German Allgäu region, has been manufacturing concrete products. Today, the fourth generation of the family is dedicated to producing concrete and precast components. BFT editorial staff met managing director Jörg Rinninger at the factory to visit the newly installed Primuss^® line for monolithic manhole bases in operation.

At Kißlegg in Baden-Württemberg, the company offers a product portfolio that is rather unusual in today‘s market environment because the range encompasses almost everything from concrete pavers to pipe systems and structural precast. In civil engineering, Rinninger even supplies the entire range of products. Reinforced concrete pipes in diameters from DN 300 to DN 3000 and manhole units up to DN 3000 in size are manufactured as complete systems and shipped to customers. The range also includes box culverts, slot drains and sedimentation structures. In the building construction segment,...
