Product Introduction

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.

Low Height Retaining Walls

Low height garden and landscape retaining walls can be built up to 4 courses - 2 ft. (0.6 m) tall on a compacted rock base that is a minimum of 6 in. (150 mm) deep and 16 in. (400 mm) wide. The first course of block is buried 3 in. (75 mm) below grade with the cores filled with rock and all courses / blocks glued together. No surcharges or slopes above the wall. Elements installed near retaining walls must be kept a minimum of 3 ft. (1 m) away from the back of the retaining wall. For taller retaining walls, see the AB Metro Classic retaining wall.

Seating Walls

In a similar manner to the layout shown above, you can easily add columns and corners to your AB Metro Seating Wall for added stability. The height for a seating wall is 3 courses - 1.5 ft (450 mm) with a cap on an existing surface, or on a compacted rock base that is a minimum of 6 in. (150 mm) deep. Using corners and columns within the wall will breakup long walls and incorporate added stability. All courses / blocks need to be glued together.
