Allan Block overview

The company offers the AB®, AB Fieldstone®, Europa Collection® and AB Aztech® Collection. Each collection, with its own sizes and colors, can be used to create retaining walls, patios, courtyard walls or concrete fences.  The AB Collection offers a smooth fluid finish that is designed for an outdoor living space.  The Europa Collection has a hand-laid stone effect, offering a unique texture that brings out the distinction in any project, according to the company.  The Fieldstone Collection comes as close as you can get to a natural stone look, offering a variety of different textures, colors and styles.  Lastly, the Aztech collection, new to the market in 2017, offers a smooth, molded face look, inspired by the old Incan walls to offer a simulated century old feeling.

What are the extra costs?

Factor in the cost of labor costs to install these concrete units as the estimates mentioned prior will only include the material costs.  Some form of reinforcement will be needed even though this is less when compared to vertical walls.  The average wall can cost upwards of $25 to $45 per square foot if you were to hire a professional contractor.  If you want an exact estimate for your project, consider getting multiple quotes from licensed contractors in your area for free at

Additional materials will be needed, including masonry adhesive, 2×4 (used for leveling), base rock, crushed rock, and decorative rock (optional for the finish).  These materials will vary depending on the project you are thinking about.

Tips to know:

Allan Blocks are concrete units manufactured in an eco-friendly manner, using sand and natural stone with integral color added during the production process.  Allan Block is made to be load barring and can be built to heights greater than the two-feet limit of stack stone.  Allan Block launched its first SRW (Segmental Retaining Wall block) in 1986.  The “Original” blocks featured a pioneering concrete block design which allowed retaining walls to be built easily and quickly without mortar joints, pins, or footings.

Allan Block walls have been designed to sit on a compacted granular base, which is designed to help save you time and money while offering a solid base for the blocks. These light-weight units are quicker and easy to install compared to natural stone.  They lock securely together to construct small landscape walls up to the large commercial retaining walls.  Allan Block’s center is usually filled using crushed gravel so as to add extra weight to the well.  Geo-grid or other fabric is commonly used with Allan Block to greatly increase the load barring capacity.

How can I save money?

Buying bulk, as with any construction material, can greatly reduce the costs by as much as 20 percent.
