LEONHARD WEISS was founded in 1900 as a pure track construction company. From these origins, an innovative, medium-sized group of companies with 4,198 employees (Germany) has developed today, which is active in almost all sectors of construction (engineering and turnkey construction, road and network construction, track infrastructure construction). The company philosophy is essentially based on the pillars of partnership-based cooperation, adherence to delivery dates, creation of values and holistic building. Intensive in-house research work forms the basis for pioneering technologies that work economically and at the same time in an environmentally friendly manner.
