The Anchor® Landmark system is a dry built segmental retaining wall system suitable for any retaining wall applications, including road and bridge schemes. The blocks provide an aesthetically pleasing face to a geogrid reinforced soil structure designed by a suitably qualified and competent engineer. The layers of geogrid reinforcement are connected positively to the blocks by a unique locking mechanical connection, giving unparalleled connection strength for challenging projects.

Anchor Landmark blocks are portrait orientated with a surface finish that gives the appearance of rugged, riven faced stone. They are available in multiple tones and slightly varying depths to emulate the character, warmth and variation of natural materials. The blocks incorporate a locating nib which automatically provides a uniform setback (3.8° face batter) and perfect alignment. Geogrid reinforcement is required for engineered walls over 1.2 m high. AG can provide a design service, and recommend that they are consulted early in the design process.

Please consult AG technical literature for further details.
