Pattern Flagstone is natural stone that has been selected and sawn to specific sizes or shapes. The packaging of these natural stone pavers makes it simple for contractors to create a seamless pattern in any landscape design. Pieces range in size from as small as 12“ x 12“ to as large as 24“ x 36“. Sizes are cut in 6“ nominal increments to allow for a mortar joint to make your design easier with pre‑configured layouts. The hottest new trend is to create outdoor spaces that flow seamlessly with your indoor spaces.
