Retaining wall systems have revolutionized the look and the construction methods of today’s retaining walls. Designed to provide a structural unit with a realistic stone-like face, the blocks are more irregular in size to provide a surface that is variable and more imitative of real stone. These blocks do have cells, but they are not organized in the same way as the standard split face. Each manufacturer will offer their own shapes, surface textures and colors that come together in their own particular system of construction. In short, they fit together accurately to increase overall strength and eliminate the need for a block core. These units have made retaining walls significantly more affordable and more beautiful, particularly when coordinated with matching pavers.
