AB Metro Patio Walls Installation - Guidelines and Limitations
Following guidelines contained in our documents and tools, you are able to build a low height retaining wall up to 2 ft. (0.6 m) tall, or a free-standing patio wall up to 3 ft. (1 m) tall. Our simple to use sets of blocks allow you to stack and glue them together to create your desired design. General guidelines require all units to be glued together using a flexible masonry adhesive, such as NP1.
