Soil nailing is a technique in which MagnumStone retaining walls are reinforced by the insertion of steel reinforcing bars or steel augers or Manta Ray anchors into the retained soils behind the wall and then the anchors are attached to the MagnumStone units with a mechanical connection.
Soil nailing is most often used when excavation of the soils behind the wall is restricted because of structure above the wall or massive positive slopes or roadways or rock out-cropping or any other reason that makes excavation prohibitive. Soil nailing could be one of the fastest growing solution for wall structures as building restrictions increase because of population growth.
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.
