Our 40MPa concrete sleepers are the standard residential specification for Perth retaining walls in stable, well-drained ground conditions. Perth's coastal strip — from Cottesloe and Scarborough to Fremantle and Rockingham — sits on Tamala Limestone and deep Spearwood Sand that drains freely and places low lateral pressure on retaining wall structures, making 40MPa the correct and most economical specification for garden walls, low boundary walls, and landscaping retaining walls in these areas.
Every sleeper is manufactured to AS 4678-2002 Earth Retaining Structures requirements, with high-tensile steel reinforcement and a minimum 40MPa compressive strength. Available in charcoal, woodgrain, and smooth finish to suit Perth's diverse architectural styles — from coastal Hamptons homes in Cottesloe to contemporary new builds in Ellenbrook and Baldivis.
For walls on reactive Guildford Clay (Midland, Armadale, Gosnells, Kelmscott), walls over 1.0m, or engineer-specified designs, see our 50MPa Concrete Sleepers — Perth WA.
