It operates one of the largest open-sky bluestone quarry in the world. The company has two sites, one in Soignies and one in Ecaussines (not operational at the moment). Since 1888, CDH supplies a broad and diversified customer base of stone/marble cutters, distributors and contractors for the end-markets of renovation and new building, mainly in Belgium, the Netherlands and France.
