French Elegance

Since 1853, we have been a major player in the production of building stone at an international level, and the leading producer of natural stone in France. Each of our stones conveys a part of our architectural heritage. Polycor is proudly recognized as a Living Heritage Company, a designation granted by the French Ministry of the Economy and Finance. This recognition testifies to our exceptional French craftsmanship. We proudly count ourselves among the select companies to have secured the protected geographical indication "Pierre de Bourgogne" (Burgundy Stone) for our products originating from this region.

A Sustainable, Recyclable, and Safe Material

Le calcaire est un matériau 100% naturel et minéral. La pierre naturelle ne relâche aucun composant chimique nocif dans l’atmosphère, ni lors de sa production, ni à l’usage. La pierre s’inscrit idéalement dans une démarche de développement durable et dans les projets de construction HQE (Haute Qualité Environnementale). Les matériaux de carrière impropres à une utilisation en pierre dimensionnelle sont utilisés en granulats, amendements ou nous servent à réaménager les sites d’extraction.
