A unique raw material:


Originally operating a ceramic tile business, it was the passion for slate and the desire to value Canadian resources that led Denis Bisson and his team to found L'Ardoisière in 1996, a company specializing in the transformation of high density slate. With the acquisition of an extraction site located in Nova Scotia, L'Ardoisière has become the reference in Quebec for all Canadian slate products.

The projects are thus made whether for a flooring, wall, counter, staircase, ... it's yours to imagine.
