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.

Case Study: Redi-Rock Gravity Wall Acts as Armour for Washed Out Gisborne Slope

When a particularly bad storm hit a shoreline road in Gisborne, monstrous waves slammed into the shoreline slope, which eroded away due to oversaturation and lack of foundational support.

The erosion washed away part of the slope and took a portion of the road with it. Finding a solution that fixed the erosion, kept the road open, and fit the project's three-month deadline without sacrificing strength was key.

Ruarangi Villas is an upscale residential development currently under construction on Mt. Albert in Auckland, New Zealand. The site promises beautiful views and easy city access but sits on a severe slope thanks to the mountainous terrain.

Originally, the project used a different retaining wall system in its design. Then the developer was introduced to Redi-Rock. Read the entire project spotlight below.

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.
