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. Flagstone provides a durable and naturally slip-resistant patio surface that will last for years.
Benefits of a Flagstone Patio:
Can be laid dry for a permeable surface
Moss, grass or a hardy ground cover can be grown between the stones
Rich color with natural variation
Random Rectangle Pattern
Selecting flagstone in a random rectangle pattern is ideal for creating a formal, organized look. The rectangle shape provides continuity in conjunction with the staggered joints that break up the monotony. When this pattern is mortared, it makes for a smooth surface for sliding chairs in and out from a dining table.
Irregular Pattern or Crazy Paving
For a more casual, organic appearance, an irregular flagstone pattern emphasizes the natural shape of the stone. Small stones or groundcover are used to fill the gaps, or it can be mortared. This layout may be more difficult to move patio furniture around on because of the rough stone edges and the series of small joints. Wide, sturdy wooden furniture is most suitable so that the chair and table legs don’t get stuck between the stones.
