LANDSCAPE, building and drainage materials manufacturer Marshalls has launched a new earth retaining wall system named Landmark.

The dry modular block segmental system with reinforced soil has a nearvertical face. It derives its strength and stability from a mechanical connection which holds the masonry and geogrids together. Marshalls claims this gives the reinforcement three times the strength it would have acting alone.

An interlocking channel and flange configuration on the masonry units locks the blocks together and offers increased resistance to overturning forces during construction and the design life of the wall.

Marshalls says the stepped face and textured finish of the masonry gives an appearance similar to natural stone.

The system can be easily adapted to produce curves, corners or changes in gradient.

It claims the system allows a more creative approach to landscape design as well as reduced labour and material costs because its dry stack construction is relatively quick and straightforward to install.

The BRE-accredited system was produced by Marshalls with retaining wall firm Anchor Wall Systems of Minnesota, USA.
