Carrières du Hainaut (CDH) is Europe’s largest quarry of Belgian blue limestone. CDH presently produces around 900,000 square metres of high quality Belgian Bluestone per year, a high-grade dimension stone produced exclusively in Belgium under European protected status. Belgian bluestone can be found in infrastructure and residential projects across the globe.

Our Bluestone platform is well positioned with reserves and resources of over 150 million tonnes of construction aggregates and over 28,000,000M³ of high quality Belgian Bluestone. The business employs over 420 people and has a proud history, dating back 130 years.

Due to its high quality and distinctive characteristics, Bluestone is a Global Heritage Resource and a sought after product that travels worldwide (unlike most aggregate products). Bluestone can be used in residential, commercial and infrastructure projects, as well as for architectural and cosmetic applications.
