ABOUT US

Leading Innovation

With a global network of producers, MagnumStone is proudly recognized as the world’s first wet cast big block hollow core retaining wall system for residential and commercial projects. With decades of industry experience, MagnumStone was developed by a contractor, for contractors, engineers, architects and manufacturers. MagnumStone sets projects up for success before they begin with free resources for any retaining wall design, from gravity and geogrid to positive connection and stormwater management. 

Complete with comprehensive, easy to use design software, estimation tools and a library of case studies, MagnumStone helps conquer projects of any size or complexity with a proven track record of success and expertise. The big blocks’ design contains 40% less concrete than solid concrete systems and delivers simple, efficient retaining walls with beautifully natural, textured facing. 

 

MagnumStone has the only multi-length gravity retaining wall extender units on the market, which enhance and encourage design creativity. MagnumStone offers profitable opportunities for producers, time-saving resources for designers and intuitive step-by-step installation guides for contractors. Renowned for versatility and long-lasting strength, MagnumStone retaining walls continue to build trusted project solutions for future generations.

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. Also, the large hollow cores provide unique internal vertical permeability value to the wall structure.

Why Use Us? What Sets Us Apart?

From the beginning, MagnumStone™ blocks were designed to make working with our system easier for everyone involved, from production, engineering and design to building and installing retaining walls. All MagnumStone™ products provide a distinct “Installation Advantage”.

The MagnumStone™ short and long gravity retaining wall extenders are one-of-a-kind products that are tailored to our system. The gravity extenders are engineered attachments for our standard blocks. This means gravity retaining walls can be built taller with interlocking extender units supporting and fortifying the base courses. 

Using hollow core MagnumStone™ blocks and extender units, we have greatly reduced the amount of concrete used in manufacturing, which also makes shipping and overall costs more efficient. Learn more here.
