Retaining walls can be built out of man-made products or natural stone products, depending on what look you desire.
To complete any segmental retaining wall design, steps add a design dimension for accessing transitional applications.
Patterned retaining walls resemble hand-laid stone walls, and will require a certain level of detail and craftsmanship to construct.
The AB Collections have been created in modular sizes to allow for easy construction of patterned walls. The base course of your patterned retaining wall should always be installed using a full course of full-sized blocks. Refer to the gravity wall instructions for a detailed description on how to install the base course. For retaining walls that require geogrid reinforcement, selection of which pattern to use is determined by the grid spacing shown on the approved plans. Use infill or approved on-site soils to backfill behind the wall rockin the reinforced zone. Using a mechanical plate compactor, compact the wall rock and infill materials behind the block in maximum 8 in.


With the first multiple-course pattern completed, use a plate compactor to compact the wall rock in the block cores and the wall rock behind the blocks. After running the plate compactor on top of the blocks and wall rock, compact the infill material immediately behind the wall.
Compaction in the block cores needs to be done regularly when working with patterned walls. Inside curved walls are easily constructed by maintaining a tight spacing at the front of the wall face. When ending a patterned wall with a corner, use a random selection of blocks to transition from the patterned courses into the AB Corner Blocks. When building an AB Ashlar Blend retaining wall, if an AB Junior Lite is not available, the AB Lite Stones can be cut to produce two (2) AB Half Lites.
Use a two (2) course pattern on retaining walls that have numerous inside and outside curves.
The Anchor™ Diamond® Step provides an aesthetically pleasing solution, integrated into the entire wall or patio.
Basic steps include: site prep and excavation, installing base material, base course, wall rock, backfill materials, geogrid - if necessary and compacting.


Compact in a path parallel to the wall, working from the front of the wall to the back of the infill material.
Three course patterns can be used for gravity walls or to top off a reinforced wall where geogrid is not required within the top three courses.
When ending a patterned wall, discontinue the pattern and randomly adjust as necessary to meet the site conditions. This can be done by using the end of a shovel to compact the wall rock, adding additional rock if necessary.
These walls can be built to retain a certain area or create a space that is more usable because of its step grade. Random patterns used on a reinforced wall require a level surface every 2 courses for proper installation of geogrid. Compact directly behind the blocks in a path parallel to the wall, working from the back of the wall to the back of the excavated area.
