100% Natural Stone

Sustainable, recyclable, healthy material, its production and implementation require low energy expenditure. It is ideally part of a sustainable development approach and HQE construction projects (High environmental quality).

Stone is a natural material that offers a varied and abundant resource. It is the first constituent of the earth's crust, which classifies it as an inexhaustible resource.

Polycor products are already present on projects HQE and BREEAM : the EPSILON offices in Villeurbanne, the Ministry of Justice Millennium 3 and 4 in Aubervilliers, the Quebec offices in Orly. The stone knows how to adapt to the RT 2020, our products have found their place on projects of BBC housing as
the Cours Saint Amour in Besançon, the Villa Montretout in Saint Cloud or a real estate complex on rue de la Pompe in Paris; but also on the first positive energy building of the Lyon area:
the Julie Victoire Daubié school group.

Natural stone is entirely derived from minerals in their unadulterated state, ensuring a healthful living environment without emissions of volatile compounds. This assurance is further underscored by the A+ rating attributed to our materials. Natural stone does not release any harmful chemical components into the atmosphere, either during its production or during use. Up to 10 times less CO2, our regional presence allows us to limit transport to the place of production / site, a clear environmental advantage for French stones compared to major import materials.

A Clean Industry

All cutting operations, both in the quarry and in the factory, are carried out using electric machines. Stone processing does not involve heating of any kind. Compared with other mineral-based building materials, such as concrete, the production of natural stone requires little energy resulting in significantly reduced CO2 emissions. No chemical additive is necessary for the transformation of the stone, or for its conservation over time, unlike other natural materials, such as wood.

For all our quarries, we are implementing a site redevelopment plan during and at the end of operation. The fulfillment of these commitments is guaranteed by a financial guarantee system controlled by the DREAL (Regional Directorate for the Environment, Planning and Housing).
