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. Find the Alta Pro retaining wall system at a dealer near you for your next large-scale project.
