Retaining Wall Patterns
AB Europa Collection retaining wall with pattern
All of the Allan Block Collections can be used to create a variety of pre-set and random patterned retaining walls. A pre-set pattern is repeated every two or three courses of block. A single course consists of a full size block, approx 8 in. (200 mm) tall. Random patterns used on a reinforced wall require a level surface every 2 or 3 courses for proper installation of geogrid. See the approved plans for which layers the geogrid reinforcement will be required.
- Patterned walls will have a 6° setback
- Walls with curves should always use the 2 course pattern to minimize cutting and fitting.
- The base course needs to be a full course of full size blocks. For each 10 ft. (3 m) length you will need 7 blocks.
Note: A base course of full size blocks (AB Classic or AB Dover) needs to be included. For each 10 ft. (3.0 m) of wall length you will need 7 full size blocks. For 10 ft. (3.0 m) of wall length for AB Capstones, you will need 7 AB Caps.
