About Kieswerk Oberbrunn
Since 1967, Kies- und Quetschwerk Oberbrunn GmbH has been extracting and processing gravel-sand in Oberbrunn, west of Munich. The raw gravel extracted in the gravel pit is processed in a gravel washing plant, with the water circulated in a closed loop. Screening and crushing plants split the material by grain size; a continuous mixer integrated into the loading plant produces plant-mixed concrete aggregate (WBZ) with a grading curve by arrangement. The product range includes concrete sand, concrete gravel, screed sand, natural sand, crushed, masonry and plaster sands, round gravel, chippings, crushed stone, frost-protection gravel, mineral mixtures, topsoil and mixed soil. Customers are mainly companies from the construction sector, in particular building construction, civil engineering and road construction; supplies are also made to private customers in the smallest quantities. In addition to loading bulk material, the plant accepts class Z0 excavated soil for backfilling and recultivates extracted areas. Delivery is carried out by forwarding partners in the Munich area and region.
