For the construction industry in central Europe, especially in Germany, the quality raw materials supplied by the Quarzwerke Group enjoy a long tradition and a well-earned favourable reputation. Thanks to its ore and mineral deposits, the Quarzwerke Group has been a capable and reliable supplier to industrial and construction companies for nearly 125 years.
The raw sand extracted from the deposits of the Quarzwerke Group is removed in such a way as to ensure maximum quality from the very outset. In the subsequent, elaborate processing steps, the silica sand is washed and classified using optical scanning and wet-end digesting. In additional refining steps, the silica sand is drained and dried or ground using iron-free milling techniques to produce our high-quality products.

The Quarzwerke Group comprises numerous production facilities in Western and Eastern Europe so transport costs to the final destination can be kept to a minimum.
