Introducing the first Eco-Friendly mortarless concrete retaining wall system - the AB Fieldstone Collection. Using recycled materials has allowed us to create a "green" retaining wall system that is safe for the environment and is able to use post consumer materials without taking away from the quality of the blocks.
AB Fieldstone is GREEN. Every block is made with over 25% of flyash.
AB Fieldstone is NATURAL. Every AB Fieldstone facing unit is cast to emulate the look and feel of natural stone.
AB Fieldstone is FRIENDLY. The blocks are made in two pieces making them lightweight and easy to handle.
The lighter-weight two-piece system makes it easy to handle. These ergonomically-friendly blocks are easy to lift from a pallet and carry across difficult job sites.
The ability to build taller gravity walls with the same installation practices as our AB Collection , there is no new installation process to learn.
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 hassle free experience.
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 longanchoring 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 compatible 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.
