Whether you are building a simple raised garden or tackling a major hillside, Allan Block Classics are easy to install and will provide just what you need. 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. The block can be used by themselves, or in an Ashlar Blended Pattern.
