Green, Natural, Friendly
AB Fieldstone is GREEN. Every block is made with locally recycled material in the back of the block. AB Fieldstone is NATURAL. Every AB Fieldstone facing unit is cast to emulate the look and feel of natural stone. Choose the look you want from our Series of styles. AB Fieldstone is FRIENDLY. The blocks are made in two pieces making them lightweight and easy to handle.
AB Fieldstones come in two pieces – a natural stone face and a universal back which anchors the blocks in place. The facing units are created with differing looks, styles and colors, which are called Series. There are currently three Series to choose from - the Sierra, Colonial and Cascade Series - with additional faces in development. The anchoring units are manufactured with local recycled materials. They are manufactured in two sizes and work with any of the facing units. This innovative new product has unlimited possibilities in style and constructability. The AB Fieldstone Collection is right at home in residential settings where retaining walls 6’ and under are typically called for, and up to the task on larger retaining walls 6’ and over.

AB Fieldstone Anchoring Units
AB Fieldstone is a multi-piece retaining wall system where each block assembly consists of a facing unit and an anchoring unit. These universal anchoring units - short anchoring unit (SAU) and long anchoring unit (LAU) - are made of recycled materials and are used with the 812 and 824 facing units. The long anchoring unit is an option for job sites that require taller walls, but do not have room for excavation and geogrid placement.
- The maximum gravity wall heights using short anchoring units, with either of the two facing units, is up to 5 ft. 8 in. (1.7 m) in good soil conditions.
- The maximum gravity wall heights using long anchoring units, with either of the two facing units, is up to 9 ft. 8 in. (3.0 m) in good soil conditions.
Good soils conditions are defined as well-graded compactible granular aggregate, with an internal angle of friction of 36° or greater. You should always consult a registered professional engineer to determine actual site specific requirements or to account for seismic loading.
Product Features
Green
The patented multi-piece AB Fieldstone system allows the use of recycled materials in each assembly without sacrificing the beautiful appearance of the facing unit. AB Fieldstone anchoring units are always buried, so using a higher percentage of recycled materials in the anchoring unit will never affect the appearance of the wall. Each anchoring unit is produced using recycled materials. Allan Block producers use recycled materials available locally.
- Materials used to manufacture the product are local raw materials that minimize fuel needed for handling and transportation.
- Due to efficient manufacturing processes, there is very little waste when producing the AB Fieldstone retaining wall product
- Improving the environmental impact using a product that is made of recycled materials.
- If upon project completion there are excess AB Fieldstone anchoring units, they can be saved and used on the next retaining wall project as they are universal units and can be used on all AB Fieldstone projects.
- AB Fieldstone retaining walls can help projects achieve LEED® points in 14 different credits.
- By using the AB Fieldstone product you can build retaining wall projects that are environmentally friendly applications to help with soil erosion and water management.
- AB Fieldstone is made of concrete, which is a durable building material that surpasses the life-expectancy of alternative (such as timbers or railroad ties). Concrete products do not contain toxic materials that are sometimes found in these treated timber and other materials.
Natural
AB Fieldstone comes as close as you can get to matching the raw beauty of natural stone. The different Series styles and the color options available give you truly unlimited design possibilities.
Friendly
The AB Fieldstone Collection has everything you need for a stylish look as well as being a recycled product. Not to mention, it also has many “Friendly” advantages:

Built-in Corners & Height Control
- The exciting advantages of the facing unit with its built-in corner and height control, where every facing unit is the exact same height, makes building with AB Fieldstone a hassel free experience.
