More questions about Concrete Sleepers...

A retaining wall concrete sleeper is a precast concrete block that is used to support and retain soil. Due to their durability and strength, they’re ideal for retaining walls. They’re also resistant to water, corrosion, and UV rays, which is why they’re so popular for retaining walls.

We boast a diverse range of concrete sleepers, including different sizes, strengths (such as 40MPA, 50MPA, 60MPA), and colours, suitable for various landscaping projects.

Woodgrain Concrete Sleeper – This type of sleeper is cost-effective and made out of timber. They also have the same level of durability as concrete sleepers whilst providing an aesthetically pleasing design.

Smooth Face Concrete Sleepers – This is a stylish option that’s often used in residential and commercial projects. These sleepers are particularly robust, having great resistance against harsh weather conditions, rot, and general deterioration.

Stacked Stone concrete sleepers – Also referred to as the rock face concrete sleeper, they have no shortage of demand. Regardless of their color, they have a pleasing textured appearance that results in a sleek finish. This sleeper type is also low-maintenance, long-lasting, and resistant to decay.

Retaining Wall Supplies is your one-stop shop for the best concrete sleepers & steel posts in Melbourne and the rest of Australia. We offer contemporary and classic designs for your retaining walls, all at competitive prices.

We are a reputable supplier, offering high-quality concrete sleepers with a focus on customer satisfaction and compliance with Australian standards.

We provide concrete sleepers in a wide range of colors. Charcoal and jasper colors offer a stylish and modern look, while natural and light gray concrete sleepers are more subtle.

Concrete sleepers are commonly used for exterior projects, such as:

  • Retaining wall construction
  • Steps or walkways
  • Feature Walls up to three meters high
  • Barrier walls for blocking wind and noise
  • Structural support for sandpits, decking, or raised garden beds
  • Edges for gardens, paths, and driveways

Concrete sleepers that are used to construct retaining walls generally last 15 to 20 years. These have one of the lengthy life spans of any retaining wall materials available on the market.

As long as you’re properly maintaining your sleepers, they should last the full 20 years.

Due to concrete sleepers being made out of reinforced concrete, they’re heavier, stronger, and require less maintenance than wooden sleepers. They also won’t warp or rot like wood and are even more environmentally friendly. As wooden sleepers are submerged in creosote which contains toxic chemicals, opting for concrete sleepers is a safer and more sustainable choice.

Concrete sleepers offer durability, low maintenance, and resistance to pests and weather, making them an excellent choice for long-lasting retaining walls.

At Retaining Wall Supplies (RWS), we provide competitively priced concrete sleepers, with costs varying depending on size, type, and quantity. Contact us for detailed pricing information.

They are commonly used for retaining walls, garden beds, and landscaping features, offering both aesthetic appeal and functional benefits.
