Bed depth is 4″-6″, heights of stone are 8″ x 8″ up to 16″x 16″, random lengths. Machined on four sides to achieve the square and rectangle appearance. Mimimal hand tooling is required to achieve this look at application. This Landscaping Stonestone has rich tones of brown, tan, buff, rust, and some blue gray. This building stone is machined on four edges to minimize tooling. The stones pictured in this application were tightly fit together for no visable mortar joint. However, you can completely change the overall look of the project by placing a mortar joint between the stones in a complimentary color. Great for retaining walls, outdoor and indoor fireplaces and house fascades.
