Gravel is obtained from and converted in our own gravel pits and local places of extraction in Altenmarkt and Linden (Germany) and processed to additives for the asphalt mixing facilities.

The operation of a sand pit in Emsbüren and a gravel pit in Wietmarschen-Lohne enables our branch Geeste-Dalum in the district of Emsland, Lower Saxony, to deliver first-class, quality controlled gravel and sand to its own construction sites as well as to customers of the road construction and civil engineering sector and the building materials industry.
