Easy Installation

The AB Collection is easy to install. These blocks dry-stack without mortar or footings. The hollow core feature makes them easier to handle and promotes good drainage behind the wall. The raised lip and notch lock each block in place and creates a natural setback Use one sized block or mix the different block sizes together in the wall to capture the look of hand laid stone. The AB Collection is right at home in residential settings where retaining walls 6 ft (1.8 m) and under are typically called for, and up to the task on larger retaining walls 6 ft (1.8 m) and over.

Patterned Retaining Walls

The design possibilities are endless. Use the blocks from the AB Collection individually or blend them together to create AB Ashlar Blend patterned retaining walls. The interlocking blocks easily fit together without any materials or tools.
