Concrete Sleepers

Retaining Walls Direct supplies premium concrete sleepers for retaining walls across Australia — available in 40MPa, 50MPa, and 60MPa strengths, with smooth, woodgrain, and charcoal finishes to suit any project or aesthetic. With 40+ years of hands-on experience in retaining wall construction, we stock sleepers in standard and custom lengths, engineered to perform in Australian soil conditions from reactive clay to sandy loam.

Our concrete sleepers are designed to work with our full range of galvanised steel H-beam and C-channel posts, giving you a complete, compatible wall system in one order. Whether you're building a garden retaining wall, a boundary wall, a driveway cut, or a commercial retaining structure, we have the right sleeper for the job.

For walls over 1m in height, near boundaries, or subject to surcharge loads, always consult a qualified structural engineer and check your local council requirements.
