If you have a large yard or outdoor space, Nicolock’s 8-inch Alta Pro retaining wall system will reinforce its beauty with functional grandeur. The Alta Pro is a bigger version of our popular Nicolock Alta Wall with blocks that are 2 inches taller and wider. This allows for expansive tiered retaining walls, garden walls, elevated seating areas and more.
