MagnumStone® Retaining Wall System

What is MagnumStone®?

MagnumStone® is the world’s first wet-cast, hollow-core, big block retaining wall system. That might sound fancy, but here’s what it really means: it’s lighter, stronger, and uses less concrete—so it’s better for the environment and easier on your install time.

Key Features:

Eco-Friendly & Smart

Uses 40% less concrete than traditional solid blocks

Lighter weight = easier and faster to install = less labor cost

Strong & Long-Lasting

Wet-cast concrete holds up better in Northwest weather

These blocks are built to last for decades, no crumbling

Natural Stone Look

You get the strength of concrete with the style of natural rock

Clean finish that adds curb appeal, not just utility

Flexible Designs

Comes with extender units for creative layouts

Great for tight corners, curves, or tall walls

Block Sizes:

Standard Block: 24″ H x 24″ D x 48″ W (covers 8 sq. ft.)

Half-High Block: 12″ H x 24″ D x 48″ W (covers 4 sq. ft.)

Step/Cap Unit: 6″ H x 24″ D x 48″ W – for top finish or stairs

Corner End Units: For finishing edges and sharp corners

Whether you’re doing a simple 2-foot wall or something serious for a sloped yard—we’ve got the right pieces for the job.
