Gravity Retaining Wall

MagnumStone Gravity Retaining Wall

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.

A core reason for their popular design is that gravity retaining walls can be built in tight areas 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.

Use the Force of Gravity Extenders

MagnumStone’s gravity retaining wall extenders offer retaining wall designers the ability to build taller gravity retaining walls by increasing the wall depth in 2 ft. or 4 ft. increments. These gravity retaining wall extenders deliver an impactful performance by allowing taller gravity retaining wall designs.

MagnumStone Gravity Extenders Minimize Excavation Area

The tongue-and-groove connection between the extenders and the back of standard MagnumStone blocks provides extra mass and versatility to enhance the strength of gravity retaining walls from the base up. One of the core benefits of MagnumStone's gravity retaining wall extenders is that they come in 2 ft. and 4 ft. units. This means that designers are never limited by the units used for construction. The base-to-height ratio of the gravity retaining wall's excavation area can be as low as 40%, which is significant compared to geogrid retaining wall designs which typically require an excavation area of 70%. With two different sizes of gravity extenders, this allows landowners to effectively use their property to its fullest extent with gravity retaining walls maximizing space closer to their property lines.

Strengthen Outside Corners with MagnumStone Gravity Extenders

Does your upcoming retaining wall project have tight outside corners, limited space and varying loads? The MagnumStone gravity retaining wall extenders' versatile sizes can overlap in tight corners for additional strength and flexibility. Outside corners are known to be a retaining wall's weakest point, therefore MagnumStone's gravity extenders can help fortify these areas.

Hollow Core Designs for Gravity Retaining Walls

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.

Exclusive Gravity Extenders

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.
