We have our own sandstone quarries in the Liège region: in Trooz, Marchin (Carrière de Triffoys) and Chanxhe (Carrière de Rivage). Our sandstone products - and in particular the grès of Triffoys - are renowned for their beautiful range of colours. Sandstone is a hard material (harder than limestone) that is used especially as building blocks and quarry stone.
