Inca Stone Peruvian Travertine Flagstone is an excellent choice for any vertical or horizontal application. Our random flagstone comes crated with two tons per crate and is sold by the weight. Unlike other flagstones, our flagstone has a gauged thickness of 2cm or 3/4". This allows a quicker and less costly installation, since our flagstone can be installed just like tile. Additionally, you are able to get a minimum of 180 square feet of coverage per one of our tons, in comparison to three plus tons of another non-gauged flagstone. Ultimately this allows you to spend less money per ton, for a much superior flagstone.
