We have a portfolio of over a 100 calcium carbonate and limestone-based products, which we supply to a wide range of end use applications. Besides ground calcium carbonates and granules, limestone aggregates, construction materials and agricultural lime we also supply new, innovative product lines based on limes, hydrates and precipitates – all produced from our natural calcium carbonates.

New and improved grades of our products are continually being developed in close co-operation with customers to meet their future needs.
