If you want an alternative to concrete interlocking for your patio, you should consider Flagstone. This kind of stone is extremely durable, so less thickness is required. Many of our varieties of flagstone are comparable in price to mid-range interlock. Consider using random flagstone in your walkway or patios to achieve a softer, more natural look in your next landscaping project.
The coverage of flagstone can be affected by the consistency of flagstone thickness, the density of flagstone, the width of gaps left between pieces laid.
