Why Use Us? What Sets Us Apart?

From the beginning, MagnumStone™ blocks are designed to take into account the requirements of everyone involved in the production, engineering, design and building of retaining walls. All MagnumStone™ products provide what we call the “Installation Advantage”.

The MagnumStone™ short and long gravity retaining wall extenders are a one-of-a-kind product. that are tailored to our system. MagnumStone™ gravity extenders allow gravity retaining walls to be built taller by attaching an extender behind the standard block. Using the MagnumStone™ block and extender units we have greatly reduced the amount of concrete used in manufacturing. This also makes shipping and overall costs more efficient. Learn more here.
