Working Out Your Retaining Wall Costs
While retaining wall materials costs will be just one consideration, they are a good place to start costing your project:
- Use pegs and a string to lay out your retaining wall.
- Measure its length.
- Determine the approximate height of the retaining wall.
- Multiply the length by the height to determine the square metres of materials you need.
Aside from determining your square metres of building materials, you will also have discovered some other important things about your retaining wall costs. If the height of your wall approaches 1 metre, assume you will need to employ a structural engineer
. Throughout Australia, the services of a structural engineer are required by law for all retaining walls over a metre in height and in some areas the minimum height may be as low as 600mm. If your retaining wall is less than 1.5 metres away from your property line or another building, you will probably need council approval to build it, no matter how high it is.
If your retaining wall is going to be substantially less than a metre in height and is located well away from the house or property line, your materials will be a big part of the cost of the project. A relatively simple retaining wall can be a viable DIY project, too, so you may want to read How to Build a Retaining Wall

Retaining Wall Materials
Some of the retaining wall materials you have to choose from include:
- Timber: Treated pine, treated hardwood and railway sleepers are most typically used.
- Concrete: Aside from poured concrete, you have standard concrete blocks and concrete bricks to choose from.
- Brick is a perennial favourite. If you've had a little bricklaying experience and your wall is not too high, you may be able to get good results. If your results are less than perfect, you can always render the bricks after you're done.
- Natural stone boulders make great retaining walls. Expect it to be more than a quick weekend project, though, because part of the art of stacking boulders is finding the perfect fit. That takes time.
- Retaining wall block systems are available that are ideal for a DIY retaining wall project..
