Charcoal Concrete Sleepers

Our charcoal concrete sleepers are the most popular choice for retaining walls across Australia — and it's easy to see why. The deep charcoal grey finish suits contemporary Australian homes, modern landscaping, and any outdoor space where a clean, premium look is the priority.

Available in 75mm standard and 100mm heavy duty thickness, all charcoal sleepers are steel-reinforced and engineered to handle the lateral loads of a properly built retaining wall. They won't fade, stain, or lose their colour over time — what you see on day one is what you'll see in 30 years.
