What Bärnreuther + Deuerlein does

Bärnreuther + Deuerlein Schotterwerke GmbH & Co. KG is a privately held, family-owned Bavarian construction-aggregates producer that quarries and processes Jurassic limestone and dolomite from the Franconian Jura. It operates seven active quarry and processing sites (Werk 1 Weickenhof through Werk 7 Hormersdorf) plus two administrative offices and a transport subsidiary (Bärnreuther Transport GmbH), giving it ten locations across the Nuremberg and Regensburg metropolitan regions and a daily throughput of approximately 10,000 tonnes. Its product portfolio spans commodity crushed stone (frost protection subbase, gravel/split, crushed sand, paving bedding, rubble stone, hydraulic engineering stones, railway sub-ballast per DB KG1/KG2 and hydraulically bound mixtures HGT/HGD), agricultural lime, RAL-certified gabion baskets and kits (including the Quattro-Box), asphalt mix via the Jura-Asphalt GmbH & Co. KG joint venture, certified disposal of contaminated mineral waste (Entsorgungsfachbetrieb, §56 KrWG with eANV), and third-party bulk-goods transport through its 110+ truck fleet with proprietary in-house fleet management software.

The business model is transaction-based per tonne or per delivery, with quote-based pricing rather than published lists. Direct enterprise field sales, centralized disposition at the Dillberg and Gräfenberg offices, and just-in-time delivery via the owned fleet underpin the go-to-market. Customers are horizontal B2B buyers — regional construction companies, civil engineering contractors, municipalities, and infrastructure project owners — augmented by a smaller private builder and landscaper segment. Quality assurance combines in-house laboratory testing at the modern Weickenhof Prüflabor with external monitoring by TU Munich MPA BAU. The company is family-managed (Bärnreuther and Steinbrecher/Deuerlein families), holds no external institutional capital, and is registered as a GmbH & Co. KG under Registergericht Nürnberg HRA 15462.
