No better sleeper for your home

Retaining walls are among the most important parts of a new home or landscaping project. They need to look right, perform well, and last for the life of your home. They are often one of the first projects undertaken and one of the costliest and hardest to fix if not done correctly the first time. For this reason, your retaining wall must last as long as possible.

We firmly believe that concrete sleepers are the superior choice for retaining walls. Their strength, durability, and resistance to rot and pests make them the ideal solution for homeowners, builders, and landscapers looking for a lasting, low-maintenance retaining wall.

Outback Sleepers last longer and look better doing it. With over 25 years' experience, we manufacture one of the strongest and most trusted concrete sleepers for retaining walls on the market.

Our Top Tips when using an Installer

Retaining walls are a significant investment, so it’s worth taking the time to choose your installer carefully. If not installed correctly, the outcomes can lead to serious structural issues, which can be catastrophic and costly to fix.

1. Get multiple quotes

You will be amazed how much the price can vary between Installers. You could be paying anywhere from $450 pm – $1500 pm depending on site access, location, and whether it is a cut or fill wall.

2. Do your due diligence

Visit each installer’s website and/or social pages and view examples of their past projects. Read online reviews and testimonials from past customers.

3. Check their licence

Always check that your installer is licensed for the work they are quoting you for. To activate your Product Warranty – your wall must be installed by a licensed wall builder.

If your builder is licensed, you have access to formal complaint and dispute resolution processes through the licensing authority, should any issues arise.

4. Know your obligations

The rules and regulations for installing a retaining wall will vary depending on the wall’s height and your location. At the beginning of your project, check with your local council to ensure you have the correct development approvals and have given appropriate notice to the neighbouring land owners.
