About Siegl GmbH
Siegl GmbH was founded in 1963 by Ludwig Siegl and is an owner-managed construction company with around 200 employees headquartered in Landshut. Its offering covers the entire value chain around the building material concrete: from raw material extraction through gravel mining to the production of ready-mixed concrete and the manufacture of precast concrete elements such as slabs, walls, balconies, stairs, columns, girders and custom-made special parts. The range is complemented by construction steel supplies including reinforcement planning, screed, earthworks, transport and heavy haulage, crane work, container services, and the rental of concrete conveying equipment. In system construction, the company realizes complete basements and commercial buildings including the installation and installation planning of the precast elements.
