Allan Block retaining walls with pattern

Retaining Wall Patterns    

All of the AB Collection blocks 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.

Note:

• 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 3 m length you will need 7 blocks.

Note: A base course of full size blocks (AB Classic) needs to be included. For each 3.0 m of wall length you will need 7 full size blocks. For 3.0 m of wall length for AB Capstones, you will need 7 AB Caps.
