MagnumStone geogrid retaining wall are used to reinforce the soil mass behind the MagnumStone units to create tall retaining wall systems. Wall structures that may require geogrid reinforcement to resist the increased pressures behind the wall are parking lots, roadways, water applications or positive slopes above. The light weight of the blocks reduces the amount of cement used and trucking to be sent to the sites. The internal drainage within the hollow core can also help increasing the permeability of the system.
Geogrids used with the appropriate lengths, layers, and compacted backfill materials will resist these active forces above and behind the wall. The use of Geogrid reinforcements with the MagnumStone system is very cost effective for very tall wall structures. For walls 4.0 ft and taller a qualified engineer should be consulted.
MagnumStone gravity retaining wall extenders also reduce the amount of concrete required compared to competitive solid gravity wall. Because of the unique hollow core design and the large spaces between extenders side by side It also reduces the amount of production and transportation costs.
MagnumStone concrete mass extenders are available in lengths of 2 and 4 feet and when chained together, the system can create extenders up to 12 feet or greater. A free-draining material (such as a #57 Stone) is placed in the MagnumStone and around each extender units for the entire wall project.
MagnumStone retaining wall is available in setbacks of 4.5, 2.4 and 0 degrees (near vertical), and in a variety of beautiful faces. Please check with your local producer for the setbacks and faces available in your region.

The MagnumStone system has a powerful and easy to use design engineering software that is free to all users. The software not only checks for wall overturning, bearing capacity, and sliding, it also provides global stability, seismic loading, in water conditions and many more analysis that are critical to a comprehensive final design.
