Retaining Walls

A Unique Combination of Speed of Install, Sustainability and Affordability

The Stonebloc retaining wall system delivers a unique combination of speed of install, strength, sustainability, and affordability. At the heart of the system is a unique concrete block. The interlocking design on the block means the blocks self align and lock together. This provides a sheer key in both horizontal directions. At 300kg each, Stonebloc is a gravity wall system which can be easily reinforced post installation to create a cantilever wall.

The sandstone finish on the blocks ensures a timeless aesthetic which complements and enhances the surrounding environment. Choose Stonebloc, New Zealand’s greenest retaining wall system.

We recently purchased Interbloc Blocks and the whole process from initial contact to delivery and installation was a breeze. The team at Interbloc were helpful, prompt and even when I increased our order after half the blocks had been delivered it wasn't a problem. The Interbloc locking system makes it easy to construct and an end product that looks great. Thanks to Dion & the team a pleasure doing business.
