The C channel is usually placed at the end of the retaining wall, whilst the H channel is normally used as a double C channel connecting two segments of sleepers. There is also 45 and 90 degree channels available.
In most cases, unless otherwise specified by an engineer, is that the post has to be buried down matching the height of the wall (50% in 50% out). For example, a 600mm high wall must have 600mm of steel in the ground. Therefore, the steel length should be 1200mm.
It is recommended that you have at least 600mm into the ground.
Yes, you can build your own retaining wall. Always check prior with your council about the regulations in your area. Be sure to research what is needed for a successful and up to code retaining wall.
Product cost does vary due to the size and variation of the wall. Feel free to contact us and we would be happy to provide you with some installer details, they will be able to cost the full install for your needs
Concrete sleepers are heavy, so installation can be difficult. Concrete Sleepers can provide solutions to help with installation such as Grab hire for a small daily rate.
Retaining walls above 1 meter must have council approval. If council approval is required, it is because a retaining wall may pose a danger to people or the environment around it unless it is properly constructed.
The only way to ensure that it does not is to have the wall designed and approved by professionals. In some areas, you will need to engage the services of a structural engineer.
In this case, you will need to:
Lodge a building application.Have a qualified drafter or architect draw your plans or an engineerHire a building certifier, who will approve your plans and make periodic inspections to ensure the retaining wall is being built according to specifications.
If you think your retaining wall may need council approval, it is probably a job best left to the experts.
In Victoria, a building permit is needed for retaining walls over 1 meter high. The landowner is responsible for ensuring a building permit is obtained and must ensure the person in charge of the building work has a copy of the approval. If they don’t have a building permit, an enforcement notice can be issued requiring the landowner to comply with any building requirements imposed which may involve removing or demolishing the structure. A breach of the building Act is serious and illegal building work can require a landowner to attend the Magistrate’s Court. Notification of current/recent illegal work may be sent to the “Municipal Building Surveyor”.
Concrete Sleepers have many benefits over their timber counterpart. There are many designs and colours to choose from and there’s even one that looks like a timber sleeper (‘The Malibu’ Woodgrain Textured Concrete Sleeper). They won’t warp, twist, significantly alter in appearance or rot and can’t be eaten by termites. Initially, concrete sleepers may be more expensive than timber sleepers, but depending on the height of the wall they can actually be a cheaper alternative as they’re stronger. For the long term it’s a no-brainer, as a timber sleeper wall WILL need to be replaced at some stage and who wants to build a Retaining Wall twice?
Each sleeper has a maximum height retained for engineering purposes.
Please refer our Engineering page for Maximum Retained Heights for all of our concrete sleepers.
