MagnumStone Positive Connection Retaining or mechanical connection between the MagnumStone units and geogrids, a single length of geogrid is wrapped through the hollow core providing equal length reinforcement at the bottom and top of a single unit. With this we are able to provide 100% coverage of the geogrid area.
The geogrid wrapped hollow core is then filled with gravel making this the ultimate geogrid positive connection. This unique positive or mechanical connection provides the system with a greater safety factor for connection when designing for heavy loads such as (DOT) roads, bridges and railways. No special costly connectors are required for this system to achieve the geogrids ultimate connection tensile strength.
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.
