Retaining Wall Regulations

1st Jul 2023

Depending on the size of the retaining wall, you may need to seek Council approval. For walls greater than 600mm high, and in some other states, 1000mm high you will need council approval and a engineer.

If not properly installed, concrete sleeping retaining walls and lean and bulge overtime. If you install your retaining walls at 600mm high and other states 1000mm high and follow our installation guidelines you will be fine, but anything over that it is best to have council approval and an engineer.

Retaining Wall Heights Melbourne

When will you need to get council approval for your retaining wall? the best thing to do is to simply ask your local council and that will only take a phone call. Height variations can differ from state to state. but here are some rough guidelines to follow:

* In New South Wales, you need permission from council to build a retaining wall higher than 600mm from ground level.

* On the Gold Coast of Queensland, you need building approval for retaining walls 1 metre or more in height.

* In Victoria, a building permit is needed for retaining walls over 1 metre high.

If you need a building permit you can presume that you will also need a structural engineer. If your engineer needs our concrete sleeper specification details, don't be afraid to reach out and ask our team.

Domestic retaining wall jobs are pretty straight forward for engineers and aren't a big job, so it will not cost much to get an engineer report.

Not only are there height regulations but there can also be regulations in relation to how close it can be to the boundary, best thing to do is simply call your local council.
