Rock Stone and Sand Yard (RSSY) stocks a large selection of Cut (Dimensional) and Irregular Flagstone. Flagstone is one of the best materials for patios primarily due to its narrow-packed joints that allow water to permeate instead of running off. Flagstone patios also have a very natural, organic look due to their shape and earthy shades of browns, reds, grays and blues. The most common types of flagstone used for paving patios are sandstone, slate and limestone. Please visit our website or stop by today for your next flagstone job.
