The steel grids are made from high strength welded galvanized wire with looped ends that pass through small precast openings in the back of each MagnumStone unit.
If the job calls for a Steel Grid connection, MagnumStone is the right choice for your retaining wall project. A single length ¾” rod is then threaded through each loop inside the hollow core to create a unique positive or mechanical connection between MagnumStone unit and steel grid. The steel grid solution will provide designers with a great option to traditional panel/steel systems with a significant installation and cost advantages to the end user.
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.
