    Concrete sleepers look great, are cost effective and ideal for small lots where space is limited. We use Australian products manufactured to Australian Standards for tough Queensland conditions. Concrete Sleeper retaining walls aren’t susceptible to water damage, rotting or termites.

    We supply and install quality, engineer designed, structural concrete sleeper retaining walls and can offer a full range of decorative sleeper colours and textures including: standard grey, standard charcoal, sandstone effect, timber-look and stack-stone effect.

    We provide a 7 year structural guarantee and most products are covered by manufacturer warranty. All Designer Image Gardens & Landscaping work is QBCC licensed and insured. Any concrete sleeper retaining wall in Brisbane over 1m requires engineer design and council approval. With years of experience, Designer Image Gardens & Landscaping have streamlined this process and will help you with any retaining wall from concept to completion.

    Limited Access? No problems! At Designer Image Gardens & Landscaping we have a variety of different sized machines which allows us to complete projects of any size.

    GENERAL CONCRETE SLEEPER WALL SPECIFICATIONS:

    Concrete sleeper walls are a counter levered system and are required to be built with a lean back of approximately 40mm per lineal metre.

    Concrete sleeper walls are constructed using hot dip galvanised steel beams. On a standard designed wall, a 100UC14.8 galvanised steel post would be suitable for wall heights up to 1.8m. For walls over 1.8m high the post specification is increased to a 150UC23.4. For walls over 2.6m high a post size of 150UC30 or 150UC37.8 is required.

    These beams are concreted into 450mm diameter pier holes to a depth of 400mm more than the total wall height. For example, a standard designed retaining wall with a height of 1m would require a 450mm diameter pier hole to a depth of 1.4m.

    Deeper piers and post size upgrades are required when building in close proximity to storm water and sewer services.

    OUR CONCRETE SLEEPER RETAINING WALLS:

    Our walls are designed to take a 1:10 batter and in cases where this is more, deeper piers and/or post size upgrades are required.

    Our retaining walls are backfilled with drainage gravel, 100mm slotted ag pipe and geotextile fabric.

    A bracket is available which allows you to construct a timber, colour bond or pool fence directly on top of the concrete sleeper retaining wall.

    Designer Image Gardens and Landscaping can paint your galvanised steel beams to better blend with the sleeper selection.

    *Please note that concrete sleeper walls are subject to engineer requirement and differ on each site.
