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. A rear lip connection system keeps the single-sided wall system secure, while a one-inch setback per row offers a solid angle for preventing erosion on hills.
Alta Pro wall blocks have a hollow core and hard-split rock face texture that looks like real quarried stone without the heft or price. Each Nicolock retaining wall is manufactured in the U.S.
