Timber Sleepers

Retaining Walls Direct supplies quality timber sleepers for retaining walls, garden edging, and landscaping projects across Australia. Timber sleepers offer a natural, warm aesthetic that suits garden beds, terraced landscapes, and low-to-medium height retaining walls where a softer look is preferred over concrete.

New to building with timber? Our full guide on how to build a timber sleeper retaining wall walks through the process from planning to finished wall.

Our timber sleepers are available in standard lengths and are compatible with our galvanised steel post range, giving you a complete wall system. Timber is a popular choice for:

• Garden bed borders and raised garden walls
• Low retaining walls up to 600mm in standard residential applications
• Landscaping projects where natural materials are preferred
• Renovation and extension of existing timber retaining walls

Not sure whether timber or concrete sleepers are right for your project? See our Retaining Wall Guides or ask our team — we've been building retaining walls for over 40 years and can point you in the right direction. You can also compare timber vs concrete sleepers to see which suits your project best. If it's the timber look you're after rather than timber itself, our woodgrain concrete sleepers give you that same warm, natural appearance without the rot, termites, or re-staining that come with real timber over time. Trade pricing available for bulk orders.

For walls over 1m or in structurally demanding applications, consult a qualified engineer. Timber sleeper longevity varies by species, treatment, soil moisture, and drainage conditions.
