Redi-Rock Block Specifications

Redi-Rock blocks are made of 4,000 PSI wet-cast, architectural grade concrete in environmentally controlled conditions and weigh in at roughly one ton each. These retaining blocks are very durable offering a longer maintenance-free service life saving time and money over the life of the wall. All J&R precast Redi-Rock products are manufactured to meet or exceed all state and ASTM standards.

Because Redi-Rock blocks are bigger and heavier, Redi-Rock walls can be built up to 24 feet high before requiring tie-in reinforcements. (depending on soil conditions) This is up to 75% higher than other systems.

When it comes to aesthetic appearance and durability, Redi-Rock looks and functions great in any application where a “natural rock” wall is desired. The durability and freeze/thaw strength of Redi-Rock is unsurpassed. Redi-Rock has a proven record of endurance and sustainability.

J&R Precast can help you with a Redi-Rock retaining wall solution from design and construction to final installation. We work one on one with our customers to become “partners” in every sense of the word. The engineer you start with will be the engineer who sees your project through to completion.

Redi-Rock Stairs

These steps are uniform in size and dimensions and are a great addition to any retaining wall project. Our Redi-Rock stairs can be used alone or with an accompanying retaining wall. At 7” tall, 4’ long, and 26” deep at their widest, these stairs are a great value and a great stair solution.

Freestanding Hollow Core Block

J&R Precast is proud to produce Redi-Rock’s freestanding hollow core block. 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. The hollow core blocks have both horizontal and vertical rebar inserts adding more reinforcement where and when needed.

J&R Precast Redi-Rock Caps

Redi-Rock Caps

Like most retaining walls, adding a cap to the top course of the wall is a nice way to finish complete the top of a wall. Caps can add an additional layer of visual dimension to the wall and also help provide definitive sightlines. Our Redi-Rock caps are 6” tall, 28” wide, and 4’ long. The Redi-Rock caps overhang our freestanding top block by 2” on each side. The Redi-Rock cap provides an enhanced aesthetic appearance with timeless charm.
