What Schwarzl-Gruppe does

Schwarzl-Gruppe is an Austrian construction-materials group headquartered in Premstätten, Styria, that extracts, processes, and supplies mineral aggregates, industrial raw materials, and ready-mix concrete across the Styrian market. The group's operations span sand, gravel, and crushed stone production (Kieswerke Premstätten and Neu Pirka), hard-rock and limestone quarrying (Steinbruch Gradenberg, Possegg, and PRONAT Preg), industrial raw-material recovery (LD Recycling GmbH processing Voestalpine converter slag and WPS Rohstoff GmbH handling fly ash and blast furnace slag), and four ready-mix concrete plants (Premstätten, Gleisdorf, Köflach, Gratkorn) producing standard and specialty grades including fire-resistant, fiber, and SCC concrete. The offering is bundled with a captive transportation and concrete-pumping fleet (Schwarzl Transport GmbH), enabling integrated raw-material-to-placement delivery. Founded in 1959 by Karl Schwarzl as an earthworks operator and sold to PORR AG in 1985, the group operates today as a wholly-owned subsidiary of the publicly listed PORR AG and serves commercial construction firms, municipalities, and private homeowners through a sales-led, consultation-based B2B/B2C channel mix, with project-based quote pricing and publicly downloadable product price lists. Following the 2024 divestiture of Schwarzl d.o.o., the group has refocused operations entirely on Austria.
