Wonder Walls

Built to Last. Trusted Since 1983.

Wonder Walls is Western Australia’s longest-established manufacturer and installer of precast reinforced concrete panel and post retaining walls. Since 1983, we’ve been the trusted choice for homeowners, builders, and landscapers looking for a strong, space-saving, and long-lasting retaining wall solution.

Our system is one of Australia’s lightest, thinnest, and strongest, designed to tackle a wide range of applications:

• Tiered retaining for sloped blocks
• Garden edges and landscape borders
• Sites with tight access or limited space
• Replacing rotted timber sleepers
• Supporting driveways and property boundaries

Why Wonder Walls?

• Proven Durability: Galvanised steel-reinforced concrete panels that won’t rot, warp, or rust.
• Efficient Installation: Quick to install, with no exposed steel, and minimal site disruption.
• DIY Friendly: Easy-to-handle panels designed for DIY installation or professional setup.
• Slim Profile: Maximise your usable land build right to the boundary.
• Value for Money: Lower supply and installation costs compared to many other systems.
• Engineered Strength: Retains up to 1.5m, backed by certified structural designs.

Our Perth-based factory and showroom are located in Carlisle, servicing the metro area from Quinns Rock to Dawesville. We also ship DIY kits across WA from Esperance to Kununurra, and even to Christmas Island.

Behind every install is a dedicated team of professionals from experienced ex-installers managing estimates and supervision, to skilled subcontractor crews with years of hands-on know-how. We don’t just aim for a good result we aim to get it right first time, every time.
