Stinkal is one of the three companies operating limestone extraction from quarries for Calais Port 2015, together with Les Carrières du Boulonnais and Les Carrières de la Vallée heureuse. Even if they are very close within Marquise basin, each quarry exploits a different limestone in terms of quality and use with a dominant color of aggregates specific to each one.
“Our color is blue grey” says Vincent Ribard, Director of Stinkal. “But the technical nature of our work is often unknown beyond the colors of our aggregates”.
