Key Features & Benefits

Contemporary Smooth Finish

A clean architectural face that delivers a premium, modern appearance suitable for both residential and commercial landscaping.

Reinforced Concrete Construction

Manufactured from reinforced concrete to provide exceptional strength, durability 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 supporting posts and joins required. This creates a cleaner finished retaining wall while improving installation efficiency on larger projects.

Won’t Rot, Warp or Attract Termites

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

Low Maintenance

No painting, staining or ongoing treatments are required. Once installed, your retaining wall is designed to provide decades of reliable performance.

Perfect For

The 2400mm sleeper is ideal for:

• Large residential retaining walls
• Commercial retaining walls
• Boundary retaining walls
• Landscape terracing
• New housing developments
• Professional landscaping projects
• Large-scale retaining wall installations

Why Choose the 2400mm Sleeper?

The 2400mm sleeper is designed for larger retaining wall projects where efficiency, appearance and structural performance are priorities. Its extended length reduces the number of 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 Smooth sleepers are designed for installation 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.
