Critical projects often require reinforced retaining walls. With the Redi-Rock Positive Connection (PC) System for reinforced walls, you can rest assured that your wall will stand the test of time. The Redi-Rock PC System:
The PC System requires only two components: the block and the geogrid. There are no special connection components that can fail or corrode, which simplifies the construction sequence and provides a rock solid connection.
Wet-cast, air-entrained concrete blocks offer greater durability and longer maintenance-free service life for reinforced walls. This in turn saves on maintenance costs over the life of the wall!
Extra strong geogrid/block connection
Provides taller wall design heights in just about every situation!
Because there are no pins or special connection components involved, installing the Redi-Rock PC System is fast and easy! Simply thread the grid through the slot in the blocks.
Redi-Rock blocks are trapezoidal in shape. This fact enables the blocks to accomplish convex and concave radii.
The patented fork slot technology was designed so contractors can use heavy machinery to pick multiple blocks at a time
Efficiently staging product on jobsites reduces handling time and is safer than hooking blocks with a chain.
Save time positioning blocks and ensure a proper fit with the interlocking knob and groove technology.
Block Cutaway Profile with Geogrid and Lifting Hooks
The Positive Connection (PC) System is a revolutionary new way to construct MSE walls. The system provides a weight-independent connection between Redi-Rock blocks and 12 in. wide strips of geogrid. The Patent Pending smooth edge technology provides extremely high connection strengths with the geogrid reinforcement. Smooth, rounded corners allow the geogrid to slide over the block edges without shredding and severing.
The PC System can easily be designed to meet AASHTO LRFD design standards.
Redi-Rock products lead the industry in texture depths at a whopping 5.5in of texture. Redi-Rock comes in three textures: Limestone, Cobblestone, and the revolutionary Ledgestone. Also, multiple colors can be achieved to meet your need.
Redi-Rock blocks utilize a knob and groove technology. This simple concept means that the entire structure is interlocked. Interface shear testing data is available in the Technical section of this website.
Our 28 In. Positive Connection (PC) Middle Block weighs 1540 lb. This block weighs as much as 3,235 Big Macs!
Redi-Rock uses the weight of the blocks to hold back the earth. This allows Redi-Rock to build taller walls than smaller block units before needing to add geogrid or tiebacks.
The Positive Connection Block is
28" wide (deep)
The Redi-Rock Positive Connection (PC) blocks provide a relief joint for the corners of our block in typical running bond installations. The relief joint provides superior performance in extremely high wall applications.
