The Art of Stone’s Rubble Blend Series by Ontario Stone Veneers (OSV) have been tastefully blended by our masons to match the traditional look and feel of rubble stone and flagstone that has been installed throughout the stone industry for many centuries. This stone utilizes natural limestone that is quarried and hand-chipped in Ontario and consists of random shape stone with an average thickness of 1”. This stone is typically installed with a grout joint and an over-grout can be used to achieve an authentic yet modern rustic  appearance.
