Our surfacing minerals
Slate Flakes
We transform shale extracted from our quarries into slate flakes of different grain sizes and different colors.
Granules
We use locally sourced hornfels, a type of metamorphic rock, to create our granulated products, which will then be used to surface bitumen shingles.
Sands
Our colored sands are designed for application on metal roof tiles. Their small particle size facilitates their application on smooth surfaces.
Powders
Our powders are a result of the valorization of our by-products. They can be used as filler products in numerous formulations.
The applications of our minerals
Covering and Waterproofing
Surfacing minerals can be used for waterproofing and as insulation products, thereby ensuring the roof’s aesthetic appeal.
Material Filler Products
Obtained from by-products, filler minerals are intended as an addition to other industrial ingredients.
Slate Mulch
Made from shale extracted from our quarries, decorative mulch is intended for application on landscaped gardens.
