About Kiemy
Kieswerk Kiemy AG has been active for more than 50 years in the extraction of primary gravel, the processing of mineral aggregates and the production of ready-mix concrete. Its scope of services also includes backfilling the extraction sites with clean excavated material via the company's own excavation landfill at the Räsch site in Düdingen. The company operates a gravel plant with processing of mineral aggregates as well as a concrete plant (ready-mix concrete plant) and also fills aggregates into big bags. Mineral construction waste such as concrete and asphalt granulate is recycled and processed into recycled gravel sand, concrete granulate and asphalt granulate. The concrete grades according to SN EN 206 (crane and pump concrete, homogeneous concrete, self-compacting concrete, lightly compactable concrete and pile concrete) are produced with ECO or ECO3 cements. The plant adjoins the Düdinger Möser nature reserve; the company's policy follows principles of sustainability, occupational safety and environmental compatibility. Customers come from the building construction, civil engineering and road construction sectors in the Düdingen region in the canton of Fribourg.
