Design Options

magnumstone-gravitywall
Gravity Wall
Gravity walls are built with the large MagnumStone blocks that use a tongue-and-grove system to lock the gravity extenders in place. They rely on their own and extended weight to hold back the earth behind them.
magnumstone-geogridwall3
Geogrid Wall
Geogrids used with the appropriate lengths, layers and compacted backfill materials will resist the active forces above and behind the wall. The use of geogrid reinforcement with the MagnumStone system is typically very cost effective.
magnumstone-mass-block
Mass Block Wall
Mass block function without reinforcing. Stable up to 1.8m height. Rapidly constructed and an efficient alternative to gabions for emergency roadside slip repair or another option where a block facing is required with limited space for reinforcing.
magnumstone-positiveconnection
Positive Connection
MagnumStone allows for the ultimate geogrid positive connection. This unique positive or mechanical connection provides the system with a greater safety factor for connection when designing for heavy loads, bridges and railways.
magnumstone-planter-wall
Planter Wall
The aesthetically pleasing plantable terraces maximise green area, which reduce the “heat island” effect. It’s unique internal drainage system makes it the prime choice for environmentally friendly and sustainable wall solutions.
magnumstone-steel-grid
Steel Grid
The MagnumStone steel grid solution provides designers with a great option, similar to traditional panel/steel systems, with significant installation and cost advantages to the end user.
magnumstone-cantilever
Cantilevered Wall
The large vertical and horizontal hollow cores of the MagnumStone units provide the permanent form for reinforcing steel and concrete, making installation easy and cost effective.
magnumstone-anchored
Soil Nailed
Soil nailing could be one of the fastest growing solutions for retaining wall structures, as building restrictions increase due to population growth.
