Gebr. Stumpp GmbH & Co. KG Straßenbau-Tiefbau

What Gebr. Stumpp GmbH & Co. KG Straßenbau-Tiefbau does

Gebr. Stumpp GmbH & Co. KG Straßenbau-Tiefbau is a family-owned German construction group headquartered in Balingen, Baden-Württemberg, founded in 1952 by Hugo Stumpp and now led in the second generation by Arne Stumpp alongside managing directors Achim Fischer and Christian Meyer-Kling. The company operates across road construction (Straßenbau), civil engineering (Tiefbau) including earthworks, soil improvement, canal and pipeline construction, building and concrete renovation (Bauwerks- und Betonsanierung), and operates its own asphalt production through subsidiaries AWB Asphaltmischwerke Balingen and AWZ Asphaltmischwerk Zimmern.

The group is vertically integrated across the asphalt and aggregates value chain: it owns two of the largest asphalt mixing plants in the region, holds equity stakes in quarry operations (Vereinigte Schotterwerke Zimmern & Bochingen, Bau Union Rottweil, Heinz Schotterwerke), maintains a large equipment fleet with an in-house workshop, and runs a central quality laboratory at the Balingen headquarters. Technical differentiators include 100% asphalt recycling capability, temperature-reduced (low-CO2) asphalt deployed ahead of the 2025 legal mandate, and WHG certification for liquid-tight surfaces and pavements. Workforce stands at approximately 200 employees across construction sites and offices.

The business model is project-based construction services revenue generated through one-time contracts with public-sector clients (municipalities, federal/state agencies), industry and commerce (including named projects for Bosch and Chiron), and private builders. Pricing is custom-quoted per project rather than tiered, with multi-year contract cadence typical for public infrastructure work. Go-to-market is direct field sales across southern Germany, supported by three branch offices (Balingen, Bondorf, Bad Dürrheim) plus an asphalt mixing plant site at Balingen-Ostdorf, with marketing primarily through the company website, social channels, and a dedicated career site. The company is a privately held Kommanditgesellschaft (KG) — registered at Amtsgericht Stuttgart HRA 410146 — with no external equity funding and growth funded organically and through selective acquisitions.
