Melbourne's reactive clay soils cause ground movement that creates unsightly and pest-prone gaps beneath boundary fences — concrete under-fence plinths are the durable, low-maintenance solution used by Melbourne fencing contractors and landscapers to eliminate this problem permanently. Retaining Walls Direct supplies 50mm concrete under-fence plinths to Melbourne homeowners and trades, delivered direct to site across metropolitan Melbourne and regional Victoria.
Our plinths match the concrete sleeper range in finish and profile — available in Lonsdale and Blackwood finishes, 2000mm long, 200mm wide, 50mm thick. They sit at ground level beneath Colorbond, timber, or composite fence lines, preventing soil wash-out, blocking pest entry, and maintaining a clean finished appearance as Melbourne's clay soils shift seasonally.
Melbourne's Class H and E reactive clays in the outer eastern suburbs (Knox, Maroondah), western growth corridors (Wyndham, Melton), and northern suburbs (Hume, Whittlesea) expand in wet winters and shrink in dry summers — creating gaps beneath fence lines that worsen over time. Plinths provide a rigid, ground-level barrier that moves with the fence posts rather than against them.
Plinths slot directly into the same galvanised steel H-beam and C-channel posts used for concrete sleeper retaining walls — no additional hardware required. Standard post spacing 1.8–2.0m. Ideal for boundary fences that share a post line with a retaining wall, common on Melbourne's sloping suburban blocks in the hills and outer suburbs.
Boundary fencing in Victoria is governed by the Fences Act 1968. Fences over 2.0m or those incorporating retaining elements may require council approval. Check with your local Melbourne council before installation. See our Engineering & Council Rules guide for further guidance.
