MagnumStone Retaining Walls

MagnumStone Retaining Walls are engineered to deliver exceptional performance from design through installation. Their hollow-core construction reduces installation time, simplifies shipping, improves drainage, and provides greater flexibility for challenging retaining wall projects. Whether you’re building commercial, municipal, or residential retaining walls, MagnumStone offers an efficient, durable solution designed for long-term performance.

Faster Installation

MagnumStone’s large-format blocks cover approximately 8 square feet per block, allowing crews to install more wall with fewer blocks. A small crew of 2–3 workers can install up to 1,000 square feet of wall per day, helping projects move from start to finish more efficiently.

Built-In Drainage

The hollow-core design provides both horizontal and vertical drainage, promoting proper water management and helping create retaining walls designed to perform for more than 100 years when installed correctly.

Fence Post Integration

Fence posts can be installed through the hollow core at the face of the wall, maximizing usable property space while eliminating the need for separate fence footings behind the retaining wall.

Simple Alignment System

SecureLug connectors provide consistent alignment and setback between blocks, helping installers achieve accurate placement while reducing installation time.

Flexible Reinforcement Options

MagnumStone supports multiple reinforcement methods, including:

• Geogrid
• Gravity Extender Units
• Hybrid reinforcement systems

These options make the system well suited for projects with limited excavation space or property line constraints.

Reduced Excavation Requirements

Using Gravity Extenders allows for a 40% base-to-height ratio, compared to the approximately 70% ratio typically required with traditional geogrid systems. This reduces excavation while maintaining wall performance.

Equipment-Friendly Installation

MagnumStone blocks can be installed using common construction equipment, including:

• Mini excavators
• Small skid steers
• Compact loaders

This makes placement efficient while minimizing equipment requirements on the job site.

Sustainable Wall Design

MagnumStone’s design supports environmentally conscious construction by allowing for:

• Plantable retaining walls
• Gravity wall designs using extenders
• Reduced land disturbance during installation

These features provide attractive, sustainable retaining wall solutions for a variety of applications.

Positive Geogrid Connection

MagnumStone is designed to provide 100% geogrid coverage, offering a secure connection throughout the retaining wall system.

Tight Curve Capabilities

The block system can achieve a minimum curve radius of 12 feet (3.7 m) for both convex and concave walls, giving designers greater flexibility while creating smooth, attractive curves.

Hollow-Core Engineering

The MagnumStone system combines:

• MagnumStone Top Units
• MagnumStone Standard Units
• Clear crushed gravel
• 2-foot Extender Units
• 4-foot Extender Units

Together, these components create a strong retaining wall system that balances structural performance with efficient installation.

Lower Shipping Costs

The hollow-core block design allows MagnumStone units to be stacked efficiently for transport, maximizing trailer capacity and reducing overall shipping costs.

Fewer Truckloads

A typical 10,000-square-foot retaining wall requires approximately 36 truckloads of block, reducing transportation needs and helping projects stay on schedule.

Maximize Every Delivery

Based on a 48,000-pound truck capacity, each load can transport approximately 280 square feet of MagnumStone block, ensuring more material arrives with every shipment and minimizing delivery interruptions.
