Redi-Rock XL is a new, hollow-core retaining block that extends the reach of the most comprehensive retaining wall system on the market, making even taller gravity walls in tight spaces a short order.

XL Block Wall Reaches 25.5 Feet

When the excavation for a Redi-Rock gravity wall to make room for a new hangar at John C. Tune Airport in Nashville, Tennessee, unearthed geotechnical issues, it was time to go back to the drawing board to design a taller wall. Read the case study to learn how retaining wall designer Clint Hines, P.E. optimized the wall with over 800 XL blocks, achieving a max height of 25.5 feet (7.8 meters).

Even though it might look a little different with its hollow-core, Redi-Rock XL blocks are compatible with all the other components of the Redi-Rock system. Start your design with XL and switch over to regular gravity blocks when design parameters allow!

Double the Face Coverage

At 36-inches (914 millimeters) tall -- twice the height of regular Redi-Rock blocks -- that means double the face coverage for each pick during installation. No big deal. Wait...that's a pretty big deal!

Same Looks You Love

Redi-Rock XL blocks come with the same natural stone textures you've grown to love in the rest of the system. Currently available in LedgestoneCobblestone, and Kingstone, Redi-Rock XL allows you to provide a natural stone appearance in an engineered package.

Curious what the XL buzz is all about?

Folks are already talking about Redi-Rock XL and the ways it expands the comfort zone for gravity retaining walls.

"XL units really help us get above the 15-foot height with maintaining the standard Redi-Rock 5-degree batter and helps us build taller structures in a narrower footprint."

"Having the flexibility to design super tall gravity walls within restricted limits on job sites with XL, in combination with the rest of the Redi-Rock system, gives you something that you can't do with any other modular block system out there."
