Concrete block retaining walls are the structural workhorses of Melbourne landscaping. Available in standard masonry blocks, split-face decorative blocks, and interlocking systems, they suit everything from utilitarian boundary walls to design-feature garden terraces.
Block Wall Types
- Standard masonry blocks — Core-filled and reinforced for structural applications. Often rendered for a smooth finish.
- Split-face blocks — Textured exposed face for a decorative look without rendering.
- Interlocking blocks — Dry-stack systems like Keystone or Adbri for DIY-friendly walls under 1m.
Cost & Engineering
Block walls cost $250–$550 per square metre in Melbourne. Core-filled reinforced block walls are the strongest option and are often specified by engineers for walls over 1 metre, particularly on reactive clay sites in Doncaster and Ringwood.
