Rocky Mountain Quartzite™ Flagstone

Rocky Mountain Quartzite™, nature’s most durable stone, comes in a variety of colors, sizes, and thicknesses for indoor and outdoor applications. Flagstone with a thickness range from 3/8″ to 1 1/4″ is most suitable for mortar set application over a concrete floor or a structurally suitable wood floor. Flagstone in a thickness range from 1 1/2″ to 2″ is ideal for dry setting in sand for exterior paving applications. Climate and area of application will determine the most suitable thickness of stone to ensure long life and low maintenance.

Dimensional Paving Stone

  • “I installed approximately 150 square feet of Rocky Mountain Quartzite stone tile from Northern Stone Supply in Utah. The product varies in thickness, but the width of the tile is cut consistently and allows for nice straight lines. I used a grout release along the edges only. The tile is also not very porous, so clean up was easy. There is a lot of variation in the tile and it can also be flipped over to change the look. The end product is rich in color and texture. An enhancer can be also be used to darken the tile and bring out the colors.”
