What Otto Alte-Teigeler does

Otto Alte-Teigeler (OAT) is a German specialist construction services company founded in 1977 and headquartered in Bietigheim/Baden, focused on joint technology, maintenance, and rehabilitation of traffic surfaces. The company serves public infrastructure owners and operators across four primary segments: road and highway authorities, bridge engineering, urban rail and tram operators, and airport operators, delivering services such as concrete road maintenance, bridge expansion joint construction, rail bedding systems, high-pressure water jetting, and surface texturing/grinding. OAT is 100% family-owned, employs 501–1,000 staff, and operates through a group structure (OAT GROUP) spanning nine German branch offices and seven wholly-owned international subsidiaries or affiliates across France, Austria, Switzerland, Poland, the Czech Republic, Slovakia, and Hungary.

The company's technical portfolio combines proprietary specialty materials with patented mechanical automation. Proprietary products include the OAT Schiene 25 cold-applicable plastic rail joint system (elastic from -30°C to +80°C), OAT KFE and OAT RKFE chamber fill elements for street and grass tracks, ETA-certified high-performance plastic bridge expansion joints (accepting up to 80 mm expansion and 40 mm compression), and a patented texture grinding machine guidance system using mechanical scanning to minimize overlap between grinding paths. Core delivery capabilities include diamond trenching for fiber-optic installation (daily outputs up to 500 m), deep concrete/asphalt cutting (up to 60 cm depth), dowel bar retrofit, and structural concrete slab re-levelling. R&D is housed in a dedicated department led by Tim Alte-Teigeler, and the company holds BASt approval for asphalt expansion joints and TÜV-certified WHG specialist status.

Revenue is generated through project-based professional services contracts, secured via public tenders, direct procurement, and long-term relationships with government agencies, airport operators, municipalities, and railway authorities. The go-to-market is enterprise field sales delivered through regional branches and subsidiaries, with no reseller or distribution model. Leadership has been jointly held since 2019 by Nina Alte-Teigeler, Ralf Alte-Teigeler, and Dr. Marko Wieland. Recent strategic activity includes a September 2025 partnership with Endura to enter the Turkish market and an August 2025 product launch of the patented texture grinding system.
