About the LEHNEN-Gruppe
The LEHNEN-Gruppe is a family-owned construction company headquartered in Sehlem (Rhineland-Palatinate) that can look back on more than 100 years of experience in civil engineering and road construction. With over 300 employees, the group covers the entire range of services: from motorway construction to federal and state roads, development of building plots, earthworks and landfill construction, sewer construction and renaturation, verge work, industrial construction, masonry construction and gabions, as well as gardening and landscaping. The group produces most of the required construction materials itself: Own quarries (quartzitic sandstone, hard rock), gravel deposits, stationary and mobile recycling, and an asphalt mixing plant with an RC parallel drum secure the value chain from raw material extraction to the finished structure. In addition to German companies (including Franz Lehnen, Gotthard Lehnen, AMM Asphaltmischwerke Mosel, LHW Liewer Hartsteinwerk, Neumagener Hartsteinwerk, Lehnen Gärten, Lehnen Solar), the group also includes the Luxembourg construction firm L-Travaux Sàrl. In 2024, the new company site in the Industrial Park Region Trier (IRT) in Föhren was inaugurated.
