Mibau/Stema Group’s main source of sand and gravel is from the plants operated by Heidelberger Sand und Kies at various locations in Northern Germany and from deposits near Aaabenraa in southern Denmark. The sand is widely used in the manufacture of concrete, road construction and pre stressed concrete products.

The sources have good material deposits, ultra-modern extraction and preparation technologies and the strictest quality checks ensure products with the highest levels of quality and consistency.
