Our 200x75mm and 200x100mm concrete sleepers are the two most widely used sizes across residential, landscaping, and light commercial retaining walls in Australia — strong, durable, low-maintenance, and compatible with standard galvanised steel posts.\u003c\/p\u003e\u003ch2\u003eWhich Size Do You Need?\u003c\/h2\u003e\u003ch3\u003e200x75mm Concrete Sleepers\u003c\/h3\u003e\u003cp\u003eThe 200x75mm sleeper is the standard choice for low to medium height retaining walls — typically up to around 900mm to 1.2m finished height depending on post spacing, soil conditions, and surcharge loads. It's the most common size for garden beds, level changes, driveway edges, and landscaping walls where loads are light and the wall is freestanding.\u003c\/p\u003e\u003ch3\u003e200x100mm Concrete Sleepers\u003c\/h3\u003e\u003cp\u003eThe 200x100mm sleeper offers greater bending strength and is the preferred choice for walls over 1.0m, walls retaining heavy or wet soils, walls near driveways or structures, and any situation where additional load capacity is required. The extra 25mm of thickness makes a significant difference to structural performance at height.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e For walls over 1.0m in height, near boundaries, structures, or with surcharge loads (driveways, vehicles, buildings), always confirm specifications with a licensed structural engineer or building certifier.
