Whatever the type of wall, the Cap Boulder is the perfect unit to finish the top course. With a front face that is identical to that of the Full Boulder, the Cap Boulder maintains continuity on the front side of the wall.
However, the back side of the boulder is recessed 8 inches to allow for the application of soil, sod, rock, mulch or any other fill material the end user deems necessary. The Cap Boulder’s sides are tapered to allow for a radius wall if desired. Available either 28″ or 38″ deep.
