In our gravel mills, we produce several thousand tonnes of stone products. These are obtained in our company-owned stone quarries through controlled detonations and are prepared using our efficient plant facilities in accordance with the requirements laid down in the technical regulations. The different stone and gravel products are loaded automatically onto several loading lines. A modern and high performance fleet of over 70 company-owned vehicles is available for deliveries. These are controlled via the latest dispatch technology.
