National roads
New construction and renovation of high-performance roads - even with ongoing traffic.

The construction of high-quality streets, paths and squares has been one of our specialties since our company was founded in 1956 - from forest roads to national roads.
What we build
The strain on our roads is constantly increasing. The increase in heavy vehicles and traffic density is putting more and more strain on our transport routes. The professional implementation of large and small road construction projects through to pedestrian zones, using high-quality materials and state-of-the-art construction technology, is one of our core competencies and focus areas.
