Make your hardscape modern, functional and dazzling with the Stonegate® Contemporary Wall System. Our double-sided retaining wall blocks come in three sizes with a trapezoidal shape that tapers in the back, making it easier to create curved structures. With the specialized pin system, you can build secure near-vertical or one-inch setback builds. Pins are sold separately. Thanks to our state-of-the-art blending technique, more than a dozen patterns are available with rich, long-lasting color that runs throughout the stone.
