What Joos-Gruppe does
Joos-Gruppe is a privately held, vertically integrated German civil engineering and road construction group headquartered in Hartheim am Rhein, Baden-Württemberg, and operating continuously since 1950. The group is structured under Joos Holding GmbH (managed by Andreas Ruf and Christoph Dürr) and comprises eight wholly-owned subsidiaries spanning core contracting (Johann Joos Tief- und Straßenbauunternehmung GmbH & Co. KG), environmental technology and demolition (Joos Umwelttechnik GmbH), structural rehabilitation (Bauwerkinstandsetzung division), slag recycling (SVB Schlackeverwertung Breisgau GmbH), gravel production (Kieswerk Haide GmbH & Co. KG), granite quarrying (Steinbruch Kirchsteige GmbH and Schwarzwald Granit / Kimo GmbH), and agricultural materials (Joos Agrar GmbH). The group employs approximately 380 staff across these entities.
The core contracting business delivers road construction, bridge construction and rehabilitation, railway infrastructure, tramway systems, canal and drainage works, demolition, and environmental remediation across approximately 50-60 active construction sites annually, with individual contract values ranging from roughly €260,000 to over €50 million (notably the €50M Umbau Bahnhof Müllheim ARGE project). The group owns one of Europe's most modern and highest-capacity asphalt mixing plants at Breisach-Oberrimsingen (operational since 2016), two gravel works, two granite quarries, and a slag processing facility, providing backward integration into raw materials supply. It holds multiple sector certifications including DB prequalification, PQ public-procurement prequalification, Güteschutz Kanalbau, Eignungsnachweis for structural concrete repair, and CE certifications for aggregates under EN standards.
Revenue is generated through competitive public-sector tenders (municipalities, Regierungspräsidium, federal agencies, DB Netz AG, Freiburger Verkehrs AG) and direct private client engagement (IKEA Karlsruhe, Bauverein Breisgau eG, badenovaWÄRMEPLUS). Pricing is project-based and non-public. The go-to-market motion is enterprise field sales with no consumer or channel-based distribution. Customers are concentrated in the Baden-Württemberg region, with a branch office in Karlsruhe extending the northern operating area; no international expansion is evidenced. Total revenue is not publicly disclosed.
