The smooth finish concrete sleeper is the choice for builders and homeowners who want a clean, flat wall face — one that can be painted, rendered, or left as-is for a minimalist concrete aesthetic. Unlike textured finishes, the smooth face gives you a blank canvas to work with, making it the most versatile sleeper in our range for architectural and contemporary landscaping applications.
At 2000x200x75mm, it's the standard size for residential retaining walls up to approximately 900mm to 1.2m in finished height, depending on post spacing, soil conditions, and surcharge loads.
Smooth finish sleepers slot into standard galvanised steel retaining wall posts. For walls up to 1.0–1.2m in standard soil, C-channel PFC posts are the cost-effective choice. For taller walls or heavier loads, H-beam universal column posts provide greater structural capacity.
Every retaining wall needs proper drainage behind it. Our retaining wall drainage kits include ag pipe, geotextile fabric, and weep holes — everything you need to protect your wall long-term.
Engineering note: For walls over 1.0m, near boundaries or structures, or with surcharge loads, always confirm specifications with a licensed structural engineer. Council approval may be required.
