Alameda cobble wall is very versatile as it can be used for a variety of applications. As a wall, you get the benefit of an ““old world”” stacked cobble wall that uses a side locking technology. As an edger, you can create the look of custom fit stones. Use it to create a beautifully accented garden planter as well for a unique landscape experience.
