We ensure the precise supply of raw materials

Natural materials are the basis of every construction. Raw material production and processing is a basic requirement for the provision of high-quality construction works for LEONHARD WEISS. Numerous shareholdings assure the independent supply of our construction sites with asphalt and concrete for the widest range of applications.

The mining and processing technology at all sites are adapted to increasing demands through constant modernization, especially those of environmental protection. Our asphalt mixing plants and concrete plants have complex electronic control systems with which recipes previously defined in preliminary laboratory testing are precisely implemented in the final product.
