The MagnumStone Cantilever retaining wall is made from an internal stem of vertical and horizontal steel-reinforced, cast-in-place concrete on a reinforced concrete footing. Our cantilever retaining walls are created with a hollow core concrete design and come in a variety of faces.
The large vertical and horizontal hollow cores of the MagnumStone units provide a great form for the steel and concrete and make the installation of your retaining wall easy and cost-effective. The reinforced footings can toe forward of the wall reducing excavation or allow for the walls to be built near the property line. Concrete reinforced MagnumStone cantilever wall structures can also be used to bear bridge structures or buildings or barriers.
MagnumStone gravity retaining wall extenders for cantilever walls also reduce the amount of concrete required compared to competitive solid gravity-wall designs. 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 of your walls.
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 cantilever retaining walls are 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. This software gives you an advantage when creating your cantilever retaining walls. The software not only checks for wall overturning, bearing capacity, and sliding, it also provides global stability, seismic loading, in water conditions, and much more analysis that is critical to a comprehensive final design.
