Raw Material

High-quality raw material deposits, the indispensable prerequisite for good quality, have been secured for the long term.

One of Europe's purest limestone deposits is at our disposal at the Hahnstätten plant. It consists of 350-million-year-old Devonian compact limestone with minimal traces of secondary minerals.

With selective mining and careful product control we can guarantee a resource for lime products that meets the most exact requirements.

The limestone deposits at the Steeden and Grevenbrück plants allow us to safely meet the specified quality requirements.
At all our sites the raw materials have been secured for decades.
