When is engineering required for retaining walls?
Typically, any retaining wall over 1m in height in Renmark requires engineering and council approval. However, this can vary, so it’s best to check with your local council. We can provide installation guidance and can quote for supplies needed for DIY projects or professional setups.
Can the concrete sleepers be cut to size?
Yes, all our sleepers can be cut to size. Please note that we do not offer a cutting service. Our sleepers fit 100uc and 150uc steel options.
For more information, please see this blog article regarding cutting your sleepers
Please can you explain the difference between an I beam and a C channel?
Sure – the C channel is for the start and finish of the wall (and for creating corners) and the I beam is for the continuation of the sleeper wall (i.e. it connects each sleeper bay). Aside from retaining wall steel posts, we also supply fence brackets for added support.
I Beams can also be known as H beams, UB (Universal Beam), joiners etc.
C Channels can also be known as end pieces, PFC, U piece etc.
What is the difference between Galvanised and Primed steel?
Our Primed steel is powder coated red and can be painted any colour you wish, or treated with rust prevention solutions.Â
Galvanised steel is easier to work with because you can put it straight into the ground. There is no need to paint or treat it, unlike Primed steel. As it’s hot dipped galvanised, it will last a long time before rusting occurs.
Do you provide installation services in Renmark?
Afraid not – we simply manufacture and supply.
Please contact our office in Adelaide at (08) 8387 9227 or message us on our Live Chat if you’d like us to recommend some installers for your local area.
We also have an installation guide on page 12 in our Product Guide.
What are the dimensions of your sleepers?
Our sleepers come in 2m and 2.4m lengths, 200mm high and they come in a range of thicknesses to cater for different wall heights.
We also manufacture 2m and 2.4m Cribs (100mm high) for each of our sleeper designs.

Yes – we can supply you with any type, size and length of steel.

How high can the sleeper wall be built?
You can build retaining walls up to 4m high using our engineered sleepers (subject to council approval and engineering).
The illustration below shows how you could construct your wall using our different 2m sleepers.
Can you retain using Under Fence Plinth’s (UFP’s)?
No – UFP’s are not engineered and designed to retain heavy compaction.
A light back fill (i.e. garden soil or bark) is fine, however if paving and concrete will be against the UFP’s then sleepers should be used instead. Please see the UFP page for more info.
UFP’s primary function is to fill the gap underneath a fence, prolong the life of the fence panel by preventing it from rusting and provide extra privacy.
What size steel do I need?
The general rule, unless otherwise stated by an engineer, is that whatever is out of the ground must be in the ground. For example, an 800mm high wall must have 800mm of steel in the ground as well. Therefore, the steel length should be 1600mm.
It is recommended that you always go a minimum of 600mm into the ground.Â
Where can I see a display of the sleepers?
