Retaining Wall System
MangumStone™ is a large wet-cast retaining wall system, cleverly engineered with a hollow core. Its hollow design uses nearly half the concrete of a solid system while maintaining all of its strength and durability. The environmental and economical advantages of the MagnumStone™ system are unprecedented in the industry.
Green Advantages
MagnumStone uses less concrete than traditional solid wall systems offering more sustainable construction options, contributing less CO2 to the environment during production and delivery process.
Production Advantages
Its unique hollow core design means less concrete to pour, making the units lighter for handling purposes and reducing the amount of cement required per block.
Transportation Advantages
MagnumStone’s light weight design maximizes each truck load to the site, reducing the number of trucks on the road, and their carbon footprint. Plus, each unit can be loaded and unloaded quickly and easily two at a time, reducing time and labor on the job site.
Installation Advantages
The large light weight hollow core MagnumStone™ units can be installed quickly, to create curves and turn corners, with smaller equipment and less labor.
Design Advantages
The MagnumStone’s large vertical and horizontal cores allow wall designers the flexibility of creating many solutions without environmentally costly side-effects.
Its unique internal drainage system, and ease of incorporating both through wall, and top of wall details makes it the prime choice for environmentally friendly wall solutions.
