Gravity retaining walls are designed to effectively utilize weight to resist load pressures. MagnumStone has developed innovative and exclusive features that make our gravity wall system the most versatile on the market.
Gravity retaining walls are a retaining wall that can be built in a tight area where there isn’t a lot of room to excavate. These structures are built with massive blocks that use a tongue-and-groove system to lock together. They rely on their own weight to hold back the earth behind them and are reinforced by our exclusive MagnumStone gravity extenders.
MagnumStone gravity 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.
MagnumStone Gravity Extenders replace Geogrid reinforcements by using a tongue-and-groove concrete system that meets or exceeds the demands of engineers. This system reduces the massive footprints demanded by cantilevered traditional gravity retaining walls and gives developers and owners greater use of land above the wall.
The concrete mass extenders use a tongue-and-groove connection to lock into the back of the retaining wall blocks. The extenders may also be locked into each other creating deeper units, allowing for flexible design and easy installation. The system’s design allows ample room immediately behind the wall for utility services.

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.
