Consistently 12 inches (305 mm) tall and 3-6 feet (915-1,829 mm) long, Grand Ledge provides the texture of snapped limestone and crisp, contemporary lines. Best suited for long straight runs or subtle curves, the large-scale blocks come together to create grandiose landscaping walls. Like all Rosetta products, the real stone textures created with wetcast concrete will have people doing a double take.
