Multiple Wall Solutions with Redi-Rock


Redi-Rock is no longer just giant blocks to build tall gravity walls like when it launched in 2000. Now, gravity, reinforced, freestanding, and hybrid walls come together to create optimized solutions.

Different Engineering Behind the Wall…


...same great appearance on the front of the wall.

When shoreline erosion undermined an old wooden crib wall along the coast of the Pacific Ocean in northern New Zealand, 49 feet (15 meters) of Mahia East Coast Road slipped down the cliff. Duracrete helped supply a reinforced solution with Redi-Rock 41in (1030mm) anchor blocks that could be tied into the cliff face despite not having room for geogrid. The 24-foot (7.3-meter) high by 46-foot (14-meter) long retaining wall used a reinforced waler beam and earth anchors to secure the 2,310-pound (1,050 kg) precast modular blocks to the rock face.

Instead of creating a cast-in-place wall to support the installation of a new primary crusher at their Kittrell, North Carolina quarry, Carolina Sunrock opted to go with a reinforced wall constructed with Redi-Rock Positive Connection blocks. The 51-foot (15.5-meter) tall wall was designed with a mechanically stabilized earth (MSE) zone that extended 57 feet (17.4 meters) behind the tallest section of the wall using 24XT Mirafi geogrid in order to reach the extreme height, as well as to support the massive live loads of the mining operation.

In a cost-analysis study, Hamilton County, Ohio realized they could save $40,000 when it came time to replace the bridge over Sycamore Creek by using Redi-Rock XL hollow-core retaining blocks instead of cast-in-place abutment walls. Redi-Rock Structures of OKI provided the hollow blocks that allowed them to achieve a height of 18 feet (5.5 meters) with the gravity walls.

The Sarjeant Co. helped developers of the Friday Harbour Resort to create 2.8 miles (4.5 kilometers) of shoreline for the 1,000 slip marina and development in Innisfil, Ontario, Canada. While only two courses of blocks show above the waterline, 16 courses of Redi-Rock blocks were used, bringing the gravity wall heights up to 24 feet (7.3 meters) tall.

In an effort to reduce their water usage and environmental footprint, the Philadelphia Zoo undertook a project to create a natural filtration system for Bird Lake. Smith Wilbert provided freestanding walls to help create a man-made wetland around Bird Lake that would maintain good water quality while greatly reducing the need for fresh water use, and fitting the historic aesthetic of the zoo.

Rather than use natural stone for benches in the walkways at Patriot Place, a 1.3-million-square-foot (120,000-square-meter) commercial development adjacent to the New England Patriots' Gillette Stadium, the Kraft Group opted to use Redi-Rock freestanding blocks and caps. The cobblestone texture and custom stain created just the right aesthetic for the project that also helped keep the development's construction schedule on time.

Capable of carrying heavy live loads, these back-to-back reinforced walls built with the Positive Connection blocks support the CN Rail in Montreal, Canada. Local supplier Graymont Materials supplied the product that helped eliminate an at-grade crossing with the Societe de Transport de Montreal (STM) light commuter Metro line.

Redi-Rock of North Dakota supplied this two-tiered, reinforced wall in the Kingstone texture for a homeowner wanting to see the valley out their picture window. The lower tier measures 16.5 feet (5 meters) tall, and runs for a length of 400 feet (122 meters), while the upper tier is 12 feet (3.7 meters) tall and 200 feet (61 meters) long.

Signature Stone provided the two-toned, Smooth texture blocks for this 15-foot (4.6-meter) tall gravity wall for the JPMorgan Chase Data Center in Broomfield, Colorado. The vertical batter wall was comprised of 60, 41 and 28in (1520, 1030, and 710mm) solid blocks.

With Redi-Rock XL Hollow-Core blocks supporting the gravity wall base of this wall and Positive Connection blocks used to tie into the soil for the upper section, this hybrid wall along Lake Michigan is able to help withstand the rising water levels and shoreline erosion. Brown's Precast supplied the Redi-Rock blocks for the job, helping a homeowner not only save their home but also greatly improve their property value.

Designing and Installing Curves, Corners & Batter Angles


With retaining walls, the details matter. The ability to bend a curve, turn a corner, or choose your batter are just three reasons why Redi-Rock is better than the rest.

Nice Curves

Because of each block's trapezoidal shape, it's easy to design and install inside or outside curves using Redi-Rock.

Sharp Corners

Whether it’s an inside or outside corner you’re turning, with Redi-Rock it will still look sharp.

Various Batter Angles

With various batter angles, you’ve got options on how best to get to the top of your wall!

Check out the construction details for best practices on corners, curves, batter angles, and more!

"We had to change the wall alignment to accommodate a lot of utilities that were very close to the wall ... it was nice to use the Redi-Rock system because there are so many specialized products."
