Description
SuperSleeper Composite Retaining Wall Sleeper
Build stronger, lighter and longer-lasting retaining walls with the SuperSleeper Composite Sleeper, an advanced alternative to traditional timber and concrete sleepers. Manufactured from high-strength fibre-reinforced polymer (FRP), these sleepers are engineered for durability, performance and ease of installation in Australian conditions.
Available in two sizes — 1950 x 205 x 60mm and 2350 x 205 x 60mm, and in two colours — Grey and Woodland Grey, this system gives you the flexibility to suit a wide range of retaining wall applications and landscape designs.
Key Features & Benefits
Lightweight yet incredibly strong — Easier to handle and install compared to concrete sleepers, reducing labour time and cost.
Engineered composite material — Made from fibre-reinforced polymer for superior durability, strength and long-term performance.
Will not rot, rust or crack — Designed to withstand harsh Australian weather conditions without deterioration.
Long design life — Built to last for decades, with expected lifespans up to 100 years when installed correctly.
Versatile landscaping solution — Suitable for retaining walls, garden beds, edging, pathways and structural landscape features.
Available Sizes & Applications
1950 x 205 x 60mm Sleeper — Suitable for retaining walls up to and exceeding 1 metre in height.
For walls 1 metre and above, engineering is required to ensure compliance and structural integrity.
2350 x 205 x 60mm Sleeper — Ideal for retaining walls between 200mm and 600mm high, making it perfect for low garden walls, edging and stepped landscapes.
Where to Use

Pathways & Edging — Ideal for defining spaces with a modern, low-maintenance finish.
Landscaping Features — Suitable for both residential and commercial outdoor projects.
Practical Information
This product is part of a complete retaining wall system, designed to be used with compatible posts and components for structural performance.
Due to the engineered nature of retaining walls, wall height limits, drainage and installation methods must be considered during planning.
As with all retaining wall products, engineering may be required depending on wall height, soil conditions and local regulations.
