At Knobel Bau, everything comes from a single source: the company extracts raw materials in its own gravel works, processes them, produces asphalt and uses them directly in construction projects.
The range of services extends from civil engineering and road construction, paving and petrol station construction to the design of outdoor facilities for commercial, public and private customers.
Through modern recycling, the company returns valuable raw materials almost completely to the cycle. Knobel Bau also produces and sells asphalt, gravel and concrete and operates one of the largest excavation backfill sites in the district.
