Hear it from a tradie...
Joe from Hammer and Shine
“We’ve been installing retaining walls for at least 5 years. The most common material these days is concrete so when the customer requested composite – I'll be honest, I was a little unsure. But we were able to install the wall and I was very impressed. We installed the wall – after the posts were in – in about 20 minutes. It’s really quick and easy to use. I’m looking forward to doing more jobs with the SuperSleeper composite sleepers.”
Hear it from a DIYer...
“We had our first small SuperSleeper retaining wall built by a professional landscaper and when we saw how easy it was to install we built our second one ourselves which was about 40 meters long. Everything fit together nice and easy and we painted it to match the Colorbond fence above it. Painting was an easy process as well – nice and quick. The retaining wall has lasted really well too, we’ve had no issues with it and it’s been easy to maintain.”

Got Questions? We’ve Got Answers
How do composite sleepers compare to concrete?
While concrete has a smoother and more industrial look, SuperSleeper composite sleepers are 4x stronger than concrete
Are they environmentally friendly?
Yes, SuperSleeper composite sleepers are designed with sustainability in mind. They help reduce reliance on traditional materials like treated timber and make 75% less Co2 emissions during the manufacturing process. Plus, their long lifespan means fewer replacements over time, which is better for the environment.
How long do they last?
SuperSleeper composite sleepers are built tough – they're designed to last decades (100+ years if installed and maintained correctly). They’re resistant to moisture, UV damage and pests, which means they won’t break down the way timber sleepers can.
Can I cut composite retaining wall products to size?
Yes, you can. Just like with timber, composite sleepers can be cut to fit your project. We recommend using a power saw with an appropriate blade and wearing safety gear when cutting and handling the material.
