Why Choose Concrete Sleepers?
Selecting the appropriate material for constructing a retaining wall is crucial, and among the various options available, concrete sleepers stand out as the most durable and low maintenance choice.
Concrete sleepers are extremely durable and strong that come available in 40 MPa and 50MPa concrete strength with either two steel bars that are N10 to N12 in size. Because of their exceptional resistance to extreme pressure and large loads, they are perfect for retaining walls. Concrete sleepers are resistant to water, fire, pests, and other difficulties that impact other materials, unlike timber sleepers, which are susceptible to problems like rotting, fading, and damage by white ants.
Ease of installation compared to cement blocks?
Installing concrete sleeper retaining walls is comparatively straightforward compared to other methods, making it an excellent DIY project for individuals with minimal construction experience. Unlike cement blocks, which may pose challenges in alignment and might not be suitable for walls exceeding 1m in height.
Concrete sleepers, available in lengths ranging from 1200mm to 3000mm, offer a smooth surface that facilitates easy stacking without compromising structural integrity. When properly installed using the right tools and techniques, retaining walls constructed with concrete sleepers require no maintenance.
Opting for concrete sleepers for your retaining wall project can save on labor costs by either undertaking the task yourself. Explore our step-by-step DIY guide to see the process of building a concrete sleeper retaining wall.
Concrete sleepers are ideal for do it yourself projects, but their longevity and low maintenance qualities also mean that they hold their value over time. As they are more resistant to water, fire, vermin, and normal wear and tear than other materials on the market. Selecting a sturdy design eliminates the need for repairs and lower ongoing wall maintenance costs.

Efflorescence is a white powdery substance that forms on the surface of masonry products such as brick, concrete, and stone when water that is trapped inside the material evaporates and leaves behind salts. It is caused by the presence of soluble salts that are present in the material, which become visible once they reach the surface and the water evaporates. Efflorescence is a common problem in masonry and can be unsightly, however, it is not a structural issue and can be easily cleaned off.
Typically, efflorescence will spontaneously disappear after one or two years. If removal is needed right away, you can get one by buying an efflorescence remover, which is available at most big-box hardware stores. Always test a product on a small area first and always follow the directions and guidelines on the product label. The integrity of the concrete products is not at risk due to efflorescence, a natural process that is typically harmless. Efflorescence is a normal element of using concrete items, despite the fact that it can be ugly and distract from the product’s aesthetics.
DON’T backfill the wall without first covering the sleepers with plastic (Forticon). Efflorescence may happen if too much water collects below the sleepers if plastic is not utilised and an agi drain at the base of the wall must also be installed to allow drainage.
Although concrete products are incredibly durable and sturdy, there are some simple maintenance guidelines to follow to make sure they continue to look great for a long time. Use a light spray of water from a garden hose to soften the stains or dirt, do not scrub with a hard bristle brush to clean the face of the sleeper if possible.
Dont’s
– NEVER clean sleepers with a pressurised water machine. Concrete capillaries can be widened by the water pressure, which can result in efflorescence.
– AVOID using chemical cleaners to clean the sleepers (other than Efflorescence Remover).
We don’t install directly but we can assist with quotes and recommend contractors to carry out the work.
