Ready to see what magic you can create with the Redi-Rock freestanding hollow-core block?

Hollow Core blocks allow for rebar reinforced walls that can be filled with concrete or crushed stone

Oh, Oh, Oh, It's Magic!

Introducing the Redi-Rock freestanding hollow core, also known as Magic blockTM. Thanks to the magic of the hollow core, these blocks can easily be filled with reinforcing steel and concrete to create a massive structure with enough strength to solve some of the most frequent challenges faced by retaining wall designers and installers, including attaching a barrier to the top of a retaining wall and creating flood protection walls

Beautiful Textures That Make Beautiful Walls

Redi-Rock blocks are cast in molds taken from actual stone, giving each gravity block a very detailed, natural texture. Contact your local retailer to discuss color options available in your area!

Ledgestone +


Ledgestone blocks area made using architectural-grade precast concrete with a texture that gives projects a random, stacked stone look. The level of detail in the texture gives Ledgestone walls the appearance of natural stone. Up to 115 square feet (10.5 square meters) of non-repeating texture is available.


Cobblestone +


Cobblestone blocks have a great stacked stone aesthetic. The texture is great for projects that need a smaller-scale look since each one-ton block features the appearance of six smaller blocks. Up to 23 square feet (2 square meters) of non-repeating texture is available.


Limestone +


Limestone blocks have a natural split limestone texture that beautifully mimics real quarried stone. These large-scale block faces look great on a variety of project applications with up to 23 square feet (2 square meters) of non-repeating texture available.

Kingstone +


Kingstone adds a fourth texture to the Redi-Rock aesthetic arsenal. Striking a balance between the grandiose scale of Limestone and rugged relief of Ledgestone, Kingstone appears weathered by water and time like the crown of a natural stone outcropping. With each Redi-Rock block looking like a large, quarried stone, Kingstone will transform retaining walls into castle-worthy walls.


What are people saying about the freestanding hollow-core block? 

Thanks to the magic of its hollow core freestanding design, these blocks solve some of the most frequent challenges faced by retaining wall designers and installers. 

"It's a specialized product that solves a real problem. There's nothing an installer could do comparably if a customer needs a barrier or median wall."
