Why Choose Redi-Rock?
Redi-Rock is a complete wall solution that uses interlocking concrete blocks to create strong, great-looking walls. Quick and easy to install, they’ll save you time and money.
Before using small blocks or gabion walls for your next road slip repair in New Zealand, imagine a different kind of solution with simple installation, natural-looking textures, and big enough blocks to build walls up to 4.5 meters (15 feet) without reinforcement.
With Redi-Rock’s large, precast modular blocks, delight customers with a retaining wall that won’t create huge excavation footprints or dig into property lines.
Most small block systems require geogrid reinforcement and deep excavations even for short retaining wall projects. But Redi-Rock’s massive weight and patented knob and groove technology allow you to create tall gravity walls when you have a tight job that backs up to the edge of a property line or house.

Use a block with a massive weight, not a massive footprint.
Three Reasons to Trust Redi-Rock for Your Next Infrastructure Retaining Wall

Simple Installation
Like giant Lego blocks, each Redi-Rock precast modular block has 0.5 square meters (5.75 square feet) of face, so installation goes faster than laying multiple smaller blocks.

Superior Aesthetics
Escape the stamped look of drycast blocks and please your customers with Redi-Rock’s natural stone look. Duracrete offers the Ledgestone and Limestone faces which are created from durable, wetcast concrete and can be colored to blend in with any surroundings.

Safer Project Sites
Installing Redi-Rock provided by Duracrete means:
- Reduced traffic management costs due to quicker installation
- Less risk of injury to crew due to machine placement instead of manual labor
- Less disruption to the residents, businesses, and other road users
