Concrete production
Concrete, as a building material in structural and civil engineering, must meet the highest demands and loads. For prefabricated concrete components, concrete paving stones or ready-mix concrete, we produce the required natural stone aggregates from the rocks diabase, greywacke and limestone in accordance with current regulations.
