What areas do you service? 

As a northern Gold Coast based business we service Gold Coast, Ipswich, Brisbane and Northern Rivers

Are there any regulations?

For walls 1.0m and below no certification or approval is needed.

For walls with a maximum height greater than 1.0m engineering and Certification is required.

We engage an independant soil tester to evaluate and assess your ground conditions and then a skilled engineer draws up detailed plans for us to build your boulder retaining wall.

This process can take up to three weeks, so when considering a retaining wall please keep this in mind.

If this service is required the cost will be itemised in your quote, we handle the rest.

What rock types do you have available?

 Our product range includes Sandstone, both random and dimensional sawn blocks and Basalt; natural and quarried. There’s no wrong choice here, we source only the best South East Queensland has to offer. We’re able to source many more products on request, please don’t hesitate to ask. We also offer a variety of extras to help transform your property including free standing edging, letterboxes and steppers. Please visit our rock types page for examples of each.

How much access is required? 

Ideally retaining walls should be completed when there is easy access to the site such as when the property is vacant prior to the slab being poured. While our skilled operators take the utmost care avoiding obstacles, it does slow us down.

At a squeeze, one of our machines can squeeze through a mere 1.6m opening, making a job possible. However, to make a job efficient and therefore cheaper for you, 3m and greater is ideal.

Aside from rock choice and meterage, access is the greatest pricing factor when building a retaining wall. That is, how close we are able to deliver products to the location where the wall is being built and consequently how far we need to cart rock and other materials via machine to the build location.

While it is possible and at times unavoidable to unload products and materials directly from the back of our truck if space is at a premium, it is certainly beneficial to be able to dump and stockpile on site, whether it be footpath or yard space.

Rock vs. timber


At first glance a quote for a timber retaining wall may appear cheaper.. However, this value is short lived due to the inherent problems of timber retaining walls. Timber retaining walls are renowned for their short lifespans, tendency to rot and termite issues. The cost to remove and replace a failed wall (especially if a house is now in the way) far outweighs doing it right the first time. With boulder walls, construction costs are once off as a properly constructed boulder retaining wall will last a lifetime.


Treated and hardwood sleepers have an average lifespan of ten years. This can be significantly less if drainage around the wall is insufficient. Timber walls are prone to failing, either as a result of poor design leading to tapping of water behind the wall or as a result of being located in areas with high levels of shade and natural water retention causing water rot. Another consideration with timber is white ants – typically CCA timber is treated with Copper Chromium arsenic, over a period of time this weathers down and leaves no white ant protection. These problems do not occur in boulder walls. A properly constructed boulder wall should last a life time – we can refer you to walls we created thirty years ago that still look as good as the day they were created.


Now this one is an easy choice timber retaining walls just don’t look as good as rock walls. The addition of a quality rock wall will add value to any property. Boulder retaining walls can be constructed using a variety of rock types and come in a variety of tones to best suit your property. Whether it’s the cool tones of sandstone or darker hues of blue metal we are sure to have an option to suit your taste and budget.
