The Wiesa Facility 3 bedrock surface mine was acquired in 2014 from ProStein. This consists of the 2 surface mines „Tiefer Bruch“ and „Bruch Kühne“, where recently the extraction of raw blocks was also done by the „Kamenzer Granit“ company. To meet the future operational plan the sealing and filling of the „Tiefer Bruch“ surface mine was started here in 2015. At this location we accept materials up to waste classification Z1.1. The remaining surface mine filling will be done by Eurovia Verkehrsbau Union GmbH.
