Each stone quarry has a million-year long history and offers an individual type of stone, typical for the location. The continuous worldwide search for new materials and new quarries makes it possible for us to constantly offer special new proposals for architecture. As a result of our own quarries and close relationships to many suppliers, we are able to guarantee the constant supply of top-quality materials. The use of innovative machines makes our quarrying efficient and precise. Within that context, we place great value upon sustainable extraction with environmentally-friendly machinery and the minimal use of explosives. Optimized logistics guarantee ecofriendly transport. It is a concern of ours to strengthen the local social sphere of each site and to protect nature.
