Steinbruch

What Steinbruch does

Steinbruch Fröstl is a third-generation family-owned open-pit quarrying business headquartered in Vienna, Austria, operating under the legal entity Josef Fröstl GesmbH. The company runs two quarries: a limestone operation at Gießhübl in Lower Austria and a dolomite operation at Wimpassing an der Leitha in Burgenland, both active since 1883 and 1974 respectively. Using multi-level blasting extraction, the company produces quality-certified construction aggregates including rock crushing sand (Felsbrechsande), rock grit (Felssplitte), base layer materials (Tragschichtmaterialien uOT/uUT), crushed rock aggregate (Felsbrechgut), trench fill material, masonry stones (Mauersteine), and water engineering and decorative stones (Wasserbau- und Ziersteine).

The business operates on a direct-to-customer distribution model with no delivery service. Customers place orders by phone or email and pick up materials directly from the quarry by appointment. Pricing is quote-based on unit volumes, with no published price list. The company holds quality certification through memberships in the Güteschutzverband der Österreichischen Kies-, Splitt- und Schotterwerke (since October 1967) and ANKÖ (Aufnahmekataster), which qualifies its products for public-sector construction tenders. Customers are primarily construction companies (including medium and large firms with 50+ year relationships for road, highway, rail, and airport runway projects), surrounding municipalities requiring materials for flood control and mountain stream reinforcement, and private home builders and garden designers purchasing masonry and decorative stones. The geographic footprint is regional, limited to Vienna, Lower Austria, and Burgenland, with no digital go-to-market beyond a basic HEROLD-hosted website.
