What Materials Can Be Used for A Retaining Wall?

If you are thinking of Building A Retaining Wall on your property, then one of the first (and most critical) decisions you will be faced with is choosing the building material. There are many available, from timber to Sandstone and concrete.

Sandstone Retaining Walls

The choice can be quite bewildering for first timers but don’t worry – we are here to help! But first, let’s talk about some basics.

  • Retaining walls are used for holding back soil so that it doesn’t slide off the property. Which is why it is crucial that it is made with durable materials and proper drainage that holds backs tons of dirt even during the rainy season.
  • You also need to know the council requirements and approvals of your area. In fact, a higher retaining wall must be designed by a structural engineer.


Durability, cost, and aesthetics are the three main factors to consider while selecting building materials for retaining walls. The most popular options are:

  1. Timber – Timber is the cheapest option and the least durable. This is perfect if your property doesn’t have a downhill gradient that puts additional pressure on the wall or if the area you live in doesn’t receive too much rain.
  2. Sandstone – Sandstone is the best looking option for a retaining wall. If you use natural sandstone boulders, then the overall cost remains relatively affordable; cut sandstone block or bricks are more expensive. All in all, these provide the most durability and give a fabulous, all-natural look to the property.
  3. Concrete – concrete blocks are also widely used and are pretty long lasting. These come as simple interlocking blocks or slabs which are most affordable and easy to install. However, if you want to step away from the grey cement look, then you have the option of picking different colours and finishing, but then the cost goes up. Another great way to lift the look of your basic wall is to use sandstone tiles as cladding.
  4. Brick – Brick is usually a bit cheaper than sandstone and concrete blocks, but they do require more installation time. A brick retaining wall is not a DIY job, and the service of a professional bricklayer is a must. If you like the red brick look, then this is a good option. However, unless built well and with proper drainage, they are not as durable as sandstone blocks or boulder or concrete blocks. One way to achieve a red brick look without compromising on durability is to add brick rendering/cladding to your concrete base!
  5. Gabion Retaining Walls – these are large stones held in a wire mesh basket and is usually used for civil road construction. They are easy to install as you can just buy them readymade and don’t need any concrete to hold them in place. While they are the most durable and easy to install, they fall short in the looks department.


Retaining walls might seem simple at first glance, but if you want them to last, then you have to build them with the right material and with professional help. Keep in mind that saving money now can cost you in the long run.

    What Our Customer Says

    From the time I rang Brisbane Rock Sales to get some names for quotes to do this sandstone wall to completion, I could not have been happier with the whole process. The price came in as a reasonable amount of money after I had received quotes to get the wooden retaining wall replaced, the stones came in a lot cheaper. We couldn’t be happier with the end product and we were very impressed with the professionalism shown. Thank you for making the process less stressful and creating such a pleasing result.
