The FRIEDRICH GROUP produces all common classified materials for road construction and civil engineering, from highly load-bearing sub-base materials to high-quality gravel base courses and pavement bedding materials. The versatile mineral aggregates can be compacted with outstanding results and demonstrate a high degree of stability. They can be installed openly or under asphalt and concrete. The metallurgical by-products that we use are processed with a specifically adjusted composition into aggregates for use in road construction and civil engineering and marketed as certified mineral building materials (StahLith® H and E). They are processed in the same way as natural mineral aggregates (e.g. gravel or sand).

Small quantities can be purchased at the Reststoffzentrum (Residual Material Centre) in Barum.
