Key Features & Benefits

Authentic Sandstone Finish

Replicates the warmth and character of natural sandstone while offering the consistency and durability of reinforced concrete.

Reinforced Concrete Construction

Engineered from reinforced concrete for exceptional strength, stability and long-term structural performance.

Enhanced 3-N12 Steel Reinforcement

The 2400mm sleeper is reinforced with three N12 steel reinforcing bars, providing increased strength across its longer span. This enhanced reinforcement allows the sleeper to be used in retaining walls up to approximately 1200mm high, subject to correct installation, drainage and site conditions.

Maximum Coverage with Fewer Joins

The 2400mm length spans greater distances between posts, reducing the number of joins required and creating a cleaner, more professional retaining wall while helping improve installation efficiency.

Won’t Rot, Warp or Attract Termites

Unlike timber sleepers, reinforced concrete won’t rot, split, warp or suffer termite damage, making it a long-lasting retaining wall solution.

Low Maintenance

No staining, sealing or painting required. Simply install and enjoy a retaining wall designed to perform for years to come.

Perfect For

The 2400mm sleeper is ideal for:

• Large residential retaining walls
• Landscape terracing
• Boundary retaining walls
• New home developments
• Commercial landscape projects
• Professional retaining wall installations

Why Choose the 2400mm Sandstone Sleeper?

The 2400mm sleeper is designed for larger retaining wall projects where efficiency, appearance and structural performance are key priorities. Its longer length reduces the number of supporting posts and joins required, creating a cleaner architectural finish while helping speed up installation.

Unlike many standard 75mm concrete sleepers, the Explorer 2400mm sleeper features 3-N12 steel reinforcement, providing additional strength across the full length of the sleeper. This enhanced reinforcement allows it to be used in retaining walls up to approximately 1200mm high under suitable conditions.

Wall height suitability is influenced by soil type, drainage, surcharge loads and installation methods. Engineering certification may be required depending on your project.

Installation Information

Explorer Sandstone sleepers are designed to be installed with compatible galvanised steel retaining wall posts.

Due to the increased length and weight of the 2400mm sleeper, mechanical lifting equipment or additional assistance may be required during installation.

Retaining walls above certain heights, supporting additional loads or located near buildings may require engineering certification. Always construct retaining walls in accordance with Australian Standards and your local council requirements.
