We are a supply-only business. Browse the ranges and prices online, or send your approved plans and quantities for a coordinated materials and freight quote. For larger orders and staged projects, see our trade and bulk retaining wall supply options.

Concrete Sleepers, Steel and Accessories for Your Materials Schedule

Order the specified components together for your concrete sleeper retaining wall:

Check your approved design and installer’s materials schedule for the required sections, lengths, quantities, connections and drainage arrangement. Backfill and any items outside our listed range should be confirmed separately.

We coordinate materials supply; structural suitability and component compatibility must be confirmed for the project before ordering.

Retaining Wall Supply for Residential, Trade and Civil Projects

We supply retaining wall materials across multiple project types throughout Victoria.

Residential Retaining Walls

Garden walls, boundary walls and small structural walls. Focus is typically cost, access, and simplicity of installation.

Landscapers

Repeat installation work requiring consistent product sizing, reliable stock availability and fast turnaround.

Builders

Program-driven projects where delays in material supply impact overall build timelines.

Civil and Commercial Projects

Engineered retaining wall systems requiring staged delivery, bulk quantities and supply coordination. Each project type requires different supply considerations. We align material supply to suit how the wall is being built.

Choosing the Right Retaining Wall Materials

Selecting the correct retaining wall system comes down to a small number of key factors.

Wall Height

Wall height directly influences steel selection and structural requirements.

Higher walls typically require larger steel sections and engineered design.

Ground Conditions

Soil type affects load on the wall. Clay and reactive soils increase pressure and require careful drainage consideration.

Load Behind the Wall

Surcharge loads such as driveways, structures or fencing increase structural demand on the system.

Access and Installation Method

Site access affects delivery, handling and the most suitable sleeper sizes.

Drainage Design

Drainage is critical. Without proper drainage, water pressure builds behind the wall and leads to failure over time.

Confirm the approved design, ground conditions, loading and drainage requirements before ordering sleepers and steel. Send your plans or materials schedule so we can quote the specified components together.

Helpful Retaining Wall Guides

Learn more about common retaining wall considerations:

What Happens When Retaining Wall Supply Goes Wrong

Most retaining wall issues are not caused by the product itself. They are caused by incorrect material selection, poor system setup, or inconsistent supply.

The impact is not minor. It affects cost, timelines and long-term performance.

Incorrect Steel Selection

Using undersized steel posts leads to structural movement over time.

Using oversized steel unnecessarily increases project cost.

Correct steel selection must align with wall height, soil conditions and load behind the wall.

Poor Drainage Setup

Lack of proper drainage creates hydrostatic pressure behind the wall.

This is the most common cause of retaining wall failure.

Every retaining wall system must include:

  • Drainage behind the wall
  • Correct backfill material
  • Separation using geofabric where required

Inconsistent Supply

Mixed product sizes or delayed deliveries slow installation and create rework.

For trade and builder projects, supply consistency directly impacts labour efficiency and project timelines.

Rework and Cost Escalation

Once a retaining wall fails or needs adjustment, costs increase quickly:

  • Removal and disposal
  • Reinstallation
  • Additional materials
  • Labour delays

The correct approach is to align materials, system components and delivery from the start.

Correct material selection and reliable supply should be aligned from the start of the project, not adjusted during installation.

Retaining wall systems must perform consistently over time, particularly where soil conditions, moisture and load can vary. Material consistency and correct system selection are critical to long-term performance.

Concrete Sleepers and Retaining Wall Steel

Our reinforced concrete sleepers use 40 MPa concrete and 2 × N12 reinforcement. Standard dimensions are:

  • 1,800 × 200 × 80 mm
  • 2,000 × 200 × 80 mm
  • 2,400 × 200 × 80 mm

Choose plain, charcoal or sandstone finishes and compare current prices online. Online prices include GST. Sleepers, steel and accessories are priced separately unless your quote states otherwise.

Galvanised retaining wall steel includes 100UC, 150UB and 150UC, plus channels and corner posts. 200UC is available by special order, subject to availability.

Check sleeper sizes, steel sections, post lengths and connections against your approved design. Ordering products together does not establish their structural suitability for a particular wall.

Structural Considerations (Practical Guidance)

Order steel to the specified section, post length, spacing and embedment in your approved design. Wall height alone is not a sizing rule: ground conditions, surcharge, wind, fence connections and the complete wall arrangement must also be considered.

Confirm the drainage layout, outlet arrangements, backfill and geofabric requirements with your designer and installer before ordering. Materials supply does not replace project-specific design or installation advice.

Use our steel selection guide, drainage guide and engineering considerations guide to prepare questions for your project team.

Victoria Materials Supply FAQs

What concrete sleeper sizes are available?

Standard lengths are 1,800 mm, 2,000 mm and 2,400 mm, with 80 mm thickness, 40 MPa concrete and 2 × N12 reinforcement. Check the required span and specification against your approved design.

Which steel section should I order?

Use your approved engineering or designer’s steel schedule. Selection depends on loads, ground conditions, spacing and connections; wall height alone is insufficient.

How is delivery priced?

Freight depends on the materials, load size, destination, access and unloading arrangements. Request a combined materials and freight quote before placing a delivery order.

Can I collect my order?
