3.0m Length Concrete Sleepers
3.0 metre concrete sleepers are built for demanding retaining wall projects that require extended spans and heavy load capacity. This size is ideal for large infrastructure, commercial landscaping and engineered walls where strength, scale and structural compliance are priorities.
Often used in council-approved applications and tiered wall systems, 3.0m sleepers help minimise joins and reduce the number of posts, making them a practical choice for long, uninterrupted runs. Walls at this span are engineer-designed and typically run on the super heavy duty post series.

Choosing 3.0m Concrete Sleepers
Length sets your post spacing, not your wall capacity. A 3.0m sleeper spans 3.0m between post centres, so fewer posts per run than shorter lengths, but each sleeper carries more load between those posts. Thickness (75mm to 100mm) and concrete strength (40MPa or 50MPa, with a 60MPa range in SA) do the structural work, and the steel post series has to match the wall height. Our sleepers are steel reinforced with two N10 or N12 ACRS bars on certified ranges and made to AS3600.
At 3m, sleepers are strictly machine-handled, so confirm crane truck or forklift access before ordering. Victoria pours 3m lengths, and interstate supply is quoted with freight, so allow lead time in the program.
Order the full wall quantity in one batch: sleeper colour can vary slightly between factory pours, and a face built from two batches shows it. If you are sizing a whole wall, the retaining wall calculator works out sleeper counts, posts and footings together, and our guide to concrete sleeper sizes explains how length, thickness and strength interact.
Are 3m sleepers a residential product?
Rarely. Walls designed around 3m spans are almost always engineered commercial or civil structures, quoted from drawings rather than off the shelf.
What posts carry a 3m span?
The super heavy duty series (200 to 310 UC sections) is the usual pairing, with the exact section and embedment set by the engineer for the height and surcharge.
