MagnumStone™ is a large wet-cast interlocking concrete block system providing an aesthetically pleasing, robust design, fast and cost-effective retaining solution.
MagnumStone is a unique hollow core mass block system, manufactured here in New Zealand, designed with the asset owner, engineer and contractor in mind. The MagnumStone system allows for robust design options to meet many different conditions and finished facing requirements. An extremely quick and easy installation process effectively removes a lot of the manual labour found with other retaining systems.
MagnumStone is the retaining wall system that ticks all the boxes:
- Quick and easy installation
- Engineered system with up to 100 year design life
- Easy to transport
- Versatile hollow core design allowing drainage at the face
- Minimises manual labour
- Less concrete than solid block systems
- Cost effective
- Flexible design options
MagnumStone™ is a Registered Trademark of CornerStone® registered in Canada.
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.
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.
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.
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 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.
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.
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.
Soil nailing could be one of the fastest growing solutions for retaining wall structures, as building restrictions increase due to population growth.
Frequently Asked Questions
The MagnumStone extenders are used only for a gravity wall where extra mass is required to make the wall stable. They nest into the back of the block to provide extra support. Extenders are not required for geogrid reinforced walls.
Currently we are stocking the LedgerStone finish which has an attractive natural rock appearance. Other face details are available on a project specific basis.
Cirtex can provide indicative design charts for initial project costing and can assist an engineer with detailed analysis. MagnumStone uses tried and trusted international design methodology.
