Today, the company is divided into five business segments:
Cement & Concrete: Cement has been produced in Wietersdorf for the last 125 years. Starting out at just a few tonnes per day, production output increased over the years to several thousand tonnes per day. Approximately one hundred years after the company was founded, vertical integration was launched in 1994, with the start of the ready-mix concrete business. Today’s igm d.o.o. was founded in 1805, making lime the de facto oldest business within the Group. However it has only been part of Wietersdorfer since 1994, following the takeover of Steirische Montanwerke. Pipe production also has a long tradition at Wietersdorfer. The company has been producing pipes since 1931. Not just the processes have changed since that time, but also the materials. Today, we distinguish between GRP pipe systems (glass-fibre reinforced plastic pipes) manufactured by Amiblu and HOBAS, and PP pipe systems (polypropylene plastic pipes), produced by Poloplast. The latest business segment is industrial minerals, represented by Calcit.
