Zero Boundry Design
We specialise in manufacturing quality retaining wall systems, specifically designed for subdivisions and inter-allotment retaining walls, with a minimum zone of influence to the envelope.
Homeowners needed a double-sided retaining wall solution so, our 400 SDS was born. Now it’s the most popular block of its variety. The top of the wall is textured and double-sided. The only kind on the market.
This system maximises buildable land on smaller subdivision lots.
Capping and Pier Blocks
Take your column, fence, blockwork, or brickwork to the next level with our pier and capping blocks, a great additional feature to finish off your LOC-A-BLOC wall.
Available in both colour ranges.

Can backfilling occur before the core filling?
No.
Core filling must occur first and be allowed to set before backfilling can occur.
The setting of the core fill only takes three days, and then backfilling can occur.
Can the 400 series components be used for marine walls?
No, this is because the core fill does not provide sufficient cover for reinforcing steel to meet marine standards for wall construction.
Our 600 series should be used to provide sufficient cover.
How many blocks to a Square metre?
400 series = 12.5
600 series = 5.5
How many blocks to a single pallet?
