Charcoal Concrete Sleeper – 2000x200x100mm Heavy Duty

Charcoal Concrete Sleeper — 2000x200x100mm Heavy Duty

Our 100mm heavy duty charcoal concrete sleeper is the structural specification for retaining walls over 1.2m, driveway walls with vehicle surcharge, and all engineer-specified designs across Australia. Where a 75mm sleeper reaches its structural limit, the 100mm steps in — delivering the additional section depth and mass needed to handle the higher lateral earth pressures that taller walls and surcharge loads impose.

With 40+ years of hands-on retaining wall experience across Australia, we supply 100mm charcoal sleepers that meet AS 4678-2002 Earth Retaining Structures requirements. Delivered direct to your site, Australia-wide.

  • Reactive clay sites in Western Sydney, Melbourne's east, Brisbane's west, Adelaide's plains, Perth's eastern suburbs
  • Any wall where long-term structural performance under high lateral load is required

Pairing with the Right Steel Post

100mm sleepers require posts with a wider channel to accommodate the increased thickness. Always pair with H-Beam (UC) steel posts — C-Channel posts are not appropriate for 100mm sleepers or walls over 1.2m. See our full guide: H-Beam vs C-Channel — Which Do You Need?

100mm vs 75mm — Which Thickness?

75mm sleepers are the standard residential thickness for walls up to approximately 1.2m with no surcharge load. Specify 100mm for walls over 1.2m, driveway walls, or any engineer-specified design. See our full guide: 75mm vs 100mm Concrete Sleepers — Which Should You Choose?

Council Approval & Compliance

Walls over 1.0m require approval in most Australian states. All walls must comply with AS 4678-2002. See our Retaining Wall Regulations — State-by-State Guide.
