Lührs GmbH

What Lührs GmbH does

Lührs GmbH is a German specialized construction contractor headquartered in Kreuzwertheim, Bavaria, focused on hydraulic engineering and waterway infrastructure. Founded in 1987 and operating as a wholly-owned subsidiary of Michael Gärtner GmbH since 2013, the company delivers four interconnected service lines: (1) engineering and water construction for locks, weirs, bridges, and harbors along German federal waterways; (2) diamond drilling and sawing services for concrete, masonry, and asphalt; (3) controlled structural demolition using low-noise, low-vibration electrohydraulic equipment; and (4) modular pontoon and push boat rental for water-based construction. The company is prequalified (valid through January 2026) for public sector construction contracts and counts Wasser- und Schifffahrtsverwaltung (WSV), Hafen Nürnberg, and municipal authorities among its clients, with active projects across Germany including the Main, Neckar, Mosel, Saar, Lahn, and increasingly Rhine/Ruhr corridors.

The company employs 15 staff, led by Managing Directors Jan Schleicher, Klemens Knörzer, and Technical Director Ronny Ihrig (appointed 2024), and operates from a campus built in 2018 in Kreuzwertheim-Wiebelbach. Revenues are generated through project-based contracts (tenders and quotes) for engineering and demolition services, supplemented by equipment rental income from the pontoon fleet. The business is wholly-owned by the Michael Gärtner group, with related companies including Leonhard Hanbuch & Söhne (monument preservation) and VSRM GmbH (traffic safety) providing cross-referral capacity. In 2019, Lührs divested its non-core Ziegelmehlproduktion (brick dust) and tennis court maintenance business to narrow focus on core hydraulic engineering services.
