Stacked flagstone has been used for centuries in small garden walls and pillars. With the award-winning Rivercrest Wall system, you get the character and flexibility of natural stone with the durability, affordability, and ease of installation of manufactured concrete. The natural appearance of Rivercrest has been achieved by casting hundreds of real stone surfaces, while the clever design makes it possible to build straight or curved walls in a variety of radius dimensions, with no cutting required, using the 4-stone random bundle. Round or square fire pits can be custom-designed using Rivercrest, or choose a simple-to-construct, Rivercrest fire pit kit. Build seat walls, water features, outdoor kitchens, or, when combined with geogrid, retaining walls up to 6ft (1.8m).
