AB Stone Mortarless Retaining Wall Blocks allow for the construction of mortarless retaining walls with a 12 degree setback.
Suitable for:
Depending on site conditions, walls can be constructed up to 1.7 m in height, using the blocks and granular fill only. Taller walls will require reinforcement, most often through the use of Geogrid or No-Fines Concrete.
CE marked and manufactured in accordance with BS EN 771-3, BBA 13/H203, ISO 9001 and ISO 14001.
Allan Block is a hollow-core, dry-stacking concrete block for the construction of retaining walls. Designed with a 12° raised front lip, which automatically establishes the setback from vertical.
Manufactured from a mixture of aggregates (65% recycled secondary aggregate content) and cement.
