What are Gravity Retaining Walls?
A gravity retaining wall exclusively uses the mass of its large interlocking concrete blocks to effectively retain soil loads from above and behind the wall. Gravity retaining walls’ long-lasting and exceptional strength protects and optimizes functional property space. The mass of MagnumStone’s big blocks hold back earth and control erosion with dynamic, world-class retaining wall solutions.
As a global industry leader, MagnumStone’s short and long gravity extenders complement its advanced block design to offer the most complete retaining wall system on the market. Trusted by the world’s top engineers, contractors and developers for walls of any shape and size, multi-length gravity extender units help retaining walls reach heights of over 40 ft. (12.2 m.) with supreme versatility.
Where are Gravity Walls Used?
-
Properties with tight spaces and limited room for excavation
-
Extending properties to maximize value and usable space
-
Building tall gravity walls closer to property lines to optimize land
-
Install behind-the-wall services with minimal land disturbance
Advantages of Gravity Retaining Walls
Make Quick work of Projects
MagnumStone blocks cover 8 sq. ft. (0.74 sq. m.) with each standard block.
Eco-Conscious Decisions
MagnumStone hollow core blocks use 40% less concrete than solid concrete systems, are easy to lift with small equipment.
Efficient Installations
Crews of 2-3 people can install over 1,200 sq. ft. (111.5 sq. m.) of MagnumStone blocks per day.
Extend the Possibilities of Gravity Walls
MagnumStone’s gravity retaining wall extenders do exactly as their name describes. They attach to the back of standard blocks. This forms an interlocking extension that fortifies and adds mass to the gravity retaining wall base courses.
Gravity extenders increase gravity wall heights by adding wall depth in 2 ft. (0.61 m.) or 4 ft. (1.2 m.) increments. Gravity wall extenders strengthen performance, so designers, installers, and landowners can trust and depend on them.
The gravity retaining wall extenders come in versatile sizes. They can overlap in tight corners for additional strength and flexibility. This fortifies and adds extra layers of protection to vulnerable areas of gravity retaining walls.
Why Use Gravity Extenders?
Build Taller Gravity Walls
Unlock the unlimited opportunities of tall gravity walls. Use the secure tongue-and-groove interlocking connection between wall blocks and multi-length extender units. Their extra mass and versatility enhance the strength of gravity retaining walls from the base up, easily reaching over 40 ft. (12.19 m.) in wall height. When building with gravity extenders, the sky is truly the limit.
Strengthen Outside Corners
Outside corners are known to be a retaining wall’s weakest point due to their tight 90-degree angles, limited space and varying direct loads. The gravity retaining wall extenders’ versatile sizes can overlap in tight corners for additional strength and flexibility to further fortify and add extra layers of protection to these traditionally vulnerable areas of a gravity wall.
Minimize Excavation Area and Reclaim Space
Gravity retaining wall extenders come in 2 ft. and 4 ft. units, so designers are never limited by their sizes for construction. No room for geogrid? Such walls can have a lower base-to-height ratio of excavation areas. This ratio can be as low as 40%, compared to typical geogrid retaining wall designs with 70%. Gain more usable space and easier access to piping and utilities behind the wall.
