Flagstone

Flagstone is a sedimentary rock that is split into layers along its bedding planes. It is mainly used for outdoor patio areas, outdoor living spaces, and walkways. Flagstone is made from a variety of natural stone like granite, sandstone, and quartzite. It comes in a wide range of colors and varies in thickness from 1" to 3". Typical flagstone colors are red, blue and buff, though exotic colors exist.
