Our innovative Sidewalk Slate mats reproduce gorgeous Old Granite and Roman Slate textures in running patterns. Cast from real stone, the ridges, lines and textures give incredible depth and character to the installation. More life-like results come from our unique three-part mat system with different sizes of slate pieces. These durable mats can be placed in a herringbone pattern to achieve a large stone Ashlar look. The final resulting appearance of hand chiseled and hand places slate is hard to tell from actual quarry material, even up close.
