MagnumStone™
Big Block Retaining Wall System

The MagnumStone™ retaining wall system was developed with the engineer, designer and installer in mind. MagnumStone’s durable, high strength concrete SecureLugs fit into the lower unit’s hollow core, allowing significant lateral movement without losing the unit interlock. Tapered sides make it easy to build tight curves and straight walls with complete accuracy. The MagnumStone’s vertical and horizontal hollow core, filled with clear crushed gravel, provides added weight, an excellent wall drainage system and a superb connection with the geosynthetic reinforcements. Magnumstone is available in two faces: Boulder face and Ledgestone.

MagnumStone ™ can be left as natural grey or custom colour stained after installation.

This product is stocked in Western Canada. Kindly contact your local sales representative for more information.
