1.2m Concrete Sleepers Sydney

1.2m concrete sleepers are the workhorse of modern Sydney retaining walls, and we supply and install them right across Greater Sydney. The 1200mm length keeps steel H-posts close enough to carry heavy soil loads while staying manageable on tight suburban sites, making 1.2m concrete sleepers ideal for garden terraces, driveway cut-and-fill and the split-level blocks so common from the Hills District to the Sutherland Shire.

Unlike timber, 1.2m concrete sleepers will not rot, warp, burn or attract termites, so a properly engineered wall can last 50 years or more in Sydney conditions. We stock plain grey, charcoal and off-white sleepers alongside textured woodgrain, stackstone and rockface finishes, letting you match a retaining wall to your home. Every installed wall is built with galvanised or powder-coated posts, correct footings, ag drainage and gravel backfill so water pressure never undermines it.

Whether you want supply-only sleepers for a DIY project or a complete engineered wall, our team handles it. For larger structural jobs we work with our retaining walls Sydney crew to manage engineering certification, council approval and drainage from start to finish.
