Road construction and underground engineering
High-level road construction and future-proof infrastructure - economic, sustainable, and according to schedule
Roads are the vibrant lifelines of our society. In a modern world, high mobility and quick connections are indispensable. Our economy and our every-day life are dependent on a powerful road network, corresponding to the steadily increasing requirements.





With well-established experience and technical know-how LEONHARD WEISS is the ideal partner for comprehensive road and traffic infrastructure construction. We offer all solutions from one source – from planning, over construction, up until maintenance. Our specialists are able to realise any kinds of roads and connections, including all complementary activities of earthwork and sewer construction, as well as the infrastructure for power, water, and media supply. Thanks to our dense network of participations in asphalting plants and our own core team for material flows (in the sense of the recycling economy) and disposal, which relies on longstanding experience and supra-regional networking, we guarantee independence and economic efficiency in construction execution.
The execution of large, highly complex infrastructure projects according to a tight schedule is our speciality. With LEONHARD WEISS you will experience the joy of building. And we create custom-made connections for our demands.
