The 200mm height allows walls to be built in clean horizontal courses, while the 75mm thickness provides a practical balance between strength, weight, and ease of handling during installation.\u003c\/p\u003e\n\u003cp\u003eBecause each sleeper course is 200mm high, wall heights can be planned in simple increments. For example, a 400mm wall will generally use two courses, a 600mm wall will generally use three courses, a 1.0m wall will generally use five courses, and a 1.2m wall will generally use six courses. Final wall design should always allow for footing depth, post size, soil type, surcharge loads, drainage, and local engineering requirements.\u003c\/p\u003e\n\u003cp\u003eThe reinforced concrete construction provides greater long-term stability than timber in ground-contact environments. Concrete does not provide a food source for termites, does not decay from moisture exposure, and does not twist or split as it ages. This makes Classic Concrete Sleepers a strong choice for permanent retaining wall projects where long service life and low maintenance are important.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose Classic Concrete Sleepers?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple finish options:\u003c\/strong\u003e Choose from smooth, timber-look, and sandstone block styles to suit the design of the project.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e40+ MPa concrete:\u003c\/strong\u003e High-strength concrete provides reliable performance for retaining wall construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 reo bar reinforcement:\u003c\/strong\u003e Internal reinforcement helps improve strength and durability across the sleeper span.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow maintenance:\u003c\/strong\u003e No staining, oiling, painting, or regular timber treatment is required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTermite resistant:\u003c\/strong\u003e Concrete is not affected by termites, borers, or other insects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeather resistant:\u003c\/strong\u003e Suitable for exposed outdoor conditions, including rain, heat, soil moisture, and changing ground conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire resistant:\u003c\/strong\u003e Concrete provides better fire resistance than timber sleepers in exposed landscape applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill not rot or warp:\u003c\/strong\u003e Unlike timber, concrete will not rot from ground contact, warp out of shape, split, or splinter over time.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDesign Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eResidential retaining walls\u003c\/li\u003e\n\u003cli\u003eGarden retaining walls\u003c\/li\u003e\n\u003cli\u003eRaised garden beds\u003c\/li\u003e\n\u003cli\u003eBoundary and fence-line retaining walls\u003c\/li\u003e\n\u003cli\u003eDriveway and front yard retaining walls\u003c\/li\u003e\n\u003cli\u003eTerraced landscaping\u003c\/li\u003e\n\u003cli\u003eFeature walls with smooth, timber-look, or sandstone block finishes\u003c\/li\u003e\n\u003cli\u003eProjects where a durable alternative to timber sleepers is preferred\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoosing the Right Finish\u003c\/h3\u003e\n\u003cp\u003eFor a clean and simple look, choose a smooth finish such as Plain Grey Smooth or Smooth Storm Grey.

Timberlook Plain and Timberlook Storm Grey provide the visual texture of timber while maintaining the durability and termite resistance of concrete.\u003c\/p\u003e\n\u003cp\u003eFor a more traditional or textured wall, choose a sandstone block finish. Sandstone Block Paperbark gives a warmer natural look, while Sandstone Block Storm Grey provides a darker, more modern stone-style finish.\u003c\/p\u003e\n\u003ch3\u003eInstallation Considerations\u003c\/h3\u003e\n\u003cp\u003eClassic Concrete Sleepers should be installed with compatible galvanised steel retaining wall posts. The correct post type, post length, footing size, and sleeper length depend on wall height, soil type, drainage, surcharge loads, site access, and engineering requirements.\u003c\/p\u003e\n\u003cp\u003eFor low walls in stable ground, C-channel posts are commonly used. For taller walls, clay soils, corners, surcharge loads, or engineer-specified projects, H-beam posts are generally preferred for additional strength and lateral resistance.\u003c\/p\u003e\n\u003cp\u003eDrainage is essential for retaining wall performance. A suitable drainage system usually includes free-draining aggregate behind the wall, geotextile fabric to separate soil from the drainage zone, and slotted agricultural pipe at the base of the wall discharging to a legal outlet. Poor drainage can increase water pressure behind the wall and may lead to movement or wall failure.\u003c\/p\u003e\n\u003ch3\u003eCompatible Products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteel post option:\u003c\/strong\u003e \u003ca href=\"\/products\/c-channel-pfc-steel-post-for-concrete-sleepers\"\u003eC-Channel PFC Steel Post for Concrete Sleepers\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-duty steel post option:\u003c\/strong\u003e \u003ca href=\"\/products\/h-beam-steel-post-for-concrete-sleepers\"\u003eH-Beam Steel Post for Concrete Sleepers\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner and end post option:\u003c\/strong\u003e \u003ca href=\"\/products\/corner-l-post-joiner-end-post-for-retaining-walls\"\u003eCorner, L-Post, Joiner and End Posts for Retaining Walls\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrainage product:\u003c\/strong\u003e \u003ca href=\"\/products\/drainage-kit-for-retaining-walls\"\u003eDrainage Kit for Retaining Walls\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFabric and wall protection:\u003c\/strong\u003e \u003ca href=\"\/products\/geotextile-fabric-wall-liner-for-retaining-walls\"\u003eGeotextile Fabric and Wall Liner for Retaining Walls\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eGuides and Resources\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation guide:\u003c\/strong\u003e \u003ca href=\"\/blogs\/news\/how-to-build-concrete-sleeper-retaining-wall\"\u003eHow to Build a Concrete Sleeper Retaining Wall\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost selection guide:\u003c\/strong\u003e \u003ca href=\"\/blogs\/news\/h-beam-vs-c-channel-steel-posts-which-do-you-need\"\u003eH-Beam vs C-Channel Steel Posts: Which Do You Need?\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost spacing guide:\u003c\/strong\u003e \u003ca href=\"\/blogs\/news\/retaining-wall-post-spacing-guide\"\u003eRetaining Wall Post Spacing Guide\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrainage guide:\u003c\/strong\u003e \u003ca href=\"\/blogs\/news\/retaining-wall-drainage-guide\"\u003eRetaining Wall Drainage Guide\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial comparison guide:\u003c\/strong\u003e \u003ca href=\"\/blogs\/news\/concrete-sleepers-vs-timber-sleepers\"\u003eConcrete Sleepers vs Timber Sleepers\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDelivery\u003c\/h3\u003e\n\u003cp\u003eClassic Concrete Sleepers are available in 1600mm, 2000mm, and 2400mm lengths, with smooth, timber-look, and sandstone block finishes available.
