What are MagnumStone Gravity Retaining Wall Extenders?
Gravity retaining wall extenders are fittingly dubbed and only used for MagnumStone’s gravity retaining wall designs. The tongue-and-groove system adds to the back of MagnumStone’s hollow core standard blocks. Thanks to extender units, the retaining wall gains an extra mass of 2 ft. (0.67 m.). and 4 ft. (1.2 m.) increments. This enhances a project’s functionality and design options.
By reducing the amount of labour required during the installation, reducing the excavation area also results in cost savings. Gravity extenders also greatly minimize excavation time and equipment expenses, which pleases landowners by minimizing land disturbance. The integrated lifting hooks make gravity extenders simple to install and transport with few tools. Designers can move closer to property lines to maximize available land.
The excavation space needed for gravity-based retaining walls employing MagnumStone gravity extenders is shown in the 3D diagrams below compared to that required for geogrid retaining walls.
ADVANTAGES OF GRAVITY RETAINING WALLS
MAKE QUICK WORK OF PROJECTS
MagnumStone blocks cover 8 sq. ft. (0.74 sq. m.) with each standard block
MagnumStone hollow core blocks use 40% less concrete than solid concrete systems, are easy to lift with small equipment
Crews of 2-3 people can install over 1,200 sq. ft. (111.5 sq. m.) of MagnumStone blocks per day
BUILD TALLER GRAVITY WALLS
With the safe tongue-and-groove interlocking connection between blocks and multiple-length extender pieces, you can create larger gravity barriers at any height. They can easily reach heights of more than 40 feet (12.19 meters) thanks to their added mass and adaptability. The sky is the limit when using gravity extenders!
STRENGTHEN OUTSIDE CORNERS
Due to their constrained space, steep 90-degree angles, and variable direct loads, outside corners are typically considered retaining walls’ weakest points. Because of their adaptable sizes, gravity retaining wall extenders can overlap in confined spaces, providing further flexibility and strength to further fortify and offer additional layers of protection to these traditionally vulnerable sections of gravity retaining walls.
MINIMIZE EXCAVATION AREA & RECLAIM SPACE
Land value is increasing dramatically along with sharp rises in infrastructure and development, as has been well-documented. Gravity extenders maximize available space. Gravity extenders are a worthwhile investment for project designs, whether they are new commercial developments, government infrastructure, or backyard restorations.
Gravity retaining wall extenders are available in 2 ft. and 4 ft. modules, so designers are never restricted in their construction sizes. Is there no room for geogrid? Gravity walls with extenders can have a base-to-height ratio of excavation areas as low as 40%, compared to 70% for traditional geogrid retaining wall designs. Increase the usable area and make it easier to access plumbing and utilities behind the wall.
DESIGN PROJECTS WITH GRAVITY EXTENDERS
Why are extenders needed for gravity retaining walls? Because the extenders are attached behind the wall, designers can plan taller gravity retaining walls. From a design perspective, this offers a straightforward solution with significantly greater latitude to construct taller walls with more distinctive features. Smaller design depth increments are possible due to the excavation depth’s ability to be planned in 2 ft. (0.67m) increments. Designers do not need to employ predetermined depth block lengths thanks to these adaptable lengths. Designers frequently use depth blocks that are excessively large for the scope of their work as a result of this.
GRAVITY EXTENDERS MAKE OUTSIDE CORNERS SIMPLER
Extenders’ adaptability is useful for complex retaining walls with tight corners, constrained space, and variable loads. Users can overlap the short and long extenders on top of one another, thanks to their flexibility. Short and long extenders are a real game-changer since outside corners are a crucial component of retaining walls that need extra strength and a well-thought-out design.
Outside corners gain extra reinforcement by alternating the extender lengths throughout each layer. Designers benefit from the clever pairing of small and long extenders since they can fit in spaces where conventional 4 ft. extenders cannot. The outside corner features of any project can benefit from an additional boost in strength and security thanks to the 2 ft. (0.67 m) and 4 ft. (1.2 m) gravity extenders.
Concrete is used 40% less by MagnumStone than conventional solid wall systems. Our method offers more environmentally friendly building solutions. It dramatically lowers CO2 emissions by needing less concrete in block manufacture, increasing transportation efficiency, accelerating installation procedures, and enabling plantable wall designs.
The hollow core MagnumStone technology is intended to reduce the amount of concrete in the centre of the unit while maintaining the same strength and allowing for more design options. Additionally, it increases the wall structure’s internal vertical permeability value for increased durability.
