CVH: our partner quarry for limestone fillers

For more than 25 years, the Carrières de la Vallée Heureuse has produced micronized limestone. Marketed by Carbocia, these fillers are used in many fields of activity.

Carrières de la Vallée Heureuse : a limestone deposit in the Pas-de-Calais

The Carrières de la Vallée Heureuse’s hard, compact limestone deposits have been worked since 1859 and extend over more than 200 hectares in the Bassin de Marquise area, half-way between Boulogne-sur-Mer and Calais.
