Retaining Walls Direct supplies premium concrete sleepers and galvanised steel posts to Canberra homeowners, builders, and landscapers — delivered direct to your site across the ACT and surrounding NSW regions including Queanbeyan, Yass, Goulburn, and the Southern Tablelands. Canberra's unique combination of reactive clay soils, frost-prone winters, and strict ACT Planning requirements creates retaining wall challenges that demand materials engineered for performance — not just appearance. With over 40 years of trade experience, we supply the materials that Canberra's leading builders specify for walls that last.
Canberra sits on a mix of reactive clay soils and weathered granite, with significant variation across suburbs. Belconnen, Gungahlin, and Tuggeranong sit on reactive clay that expands during wet winters and contracts in dry summers. Canberra's cold winters also introduce freeze-thaw cycling that can damage lower-strength concrete sleepers over time — making 60MPa the preferred specification for ACT projects. In the ACT, retaining walls over 1.0m require a building approval and structural engineer's certification. Key references:
