Introduction to Sandstone Retaining Wall Construction
At JMT Earthworks, we specialise in building long-lasting sandstone retaining walls that not only serve a practical purpose but also elevate the visual appeal of your outdoor space. Sandstone is a timeless, durable material that blends seamlessly with the Gold Coast’s natural landscape. Whether you’re levelling a sloped block, creating garden terraces, or preventing soil erosion, sandstone retaining walls are both a functional and aesthetic solution.
Factors Affecting Sandstone Wall Price
The cost of a sandstone retaining wall can vary greatly depending on several factors:
- Grade of Sandstone: Higher-grade (A-grade) sandstone blocks are more durable and consistent in size and colour, which can make installation easier but slightly more expensive.
- Size and Quantity: The total wall size, in square or linear metres, will significantly influence the price.
- Delivery Costs: Larger orders or difficult-to-access sites may incur higher delivery fees.
- Finishing Options: Honed or sawn sandstone finishes cost more than rough-cut options.
- Site Access & Complexity: Steep sites or those requiring excavation will increase labour and machinery costs.
- GST & Other Fees: Don’t forget to factor in GST and possible council approvals.
On average, Gold Coast sandstone retaining walls typically range from $250 to $600 per square metre, depending on these variables.
Choosing the Right Builder on the Gold Coast

- Expertise in working with sandstone

At JMT, we pride ourselves on delivering high-quality work on time and on budget—with honest, up-front pricing and no hidden fees.
Sandstone Quality and Grade
Not all sandstone is created equal. Choosing the right grade ensures durability, weather resistance, and aesthetic consistency:
- A-Grade: Smooth cut, consistent colour, easy to stack – best for structural walls.
- B-Grade: More irregular, suited for rustic or budget-friendly builds.
- Random Cut or Rock-Faced: Ideal for decorative projects or natural-style gardens.
JMT Earthworks sources only premium sandstone from trusted local quarries to ensure quality, durability, and timeless appeal.
Design and Construction Considerations
Several design and site considerations will impact both cost and success:
- Drainage: Proper drainage is essential to avoid pressure build-up and structural failure.
- Footings and Foundation: A solid base and compacted footing material are critical.
- Wall Height: Walls over 1 metre may require engineering certification or council consent.
- Terracing: Multi-level designs can increase both aesthetic value and complexity.
JMT will guide you through the design process and make recommendations based on your property, soil type, and intended wall function.
Measuring and Ordering Materials
Accurate site measurement is essential to avoid wastage or shortage:
- Length x Height = Area (to calculate how many blocks are needed)
- Add 10–15% buffer for cutting and breakage
- Consider additional materials like geogrid, agi pipe, and backfill gravel
JMT Earthworks offers a complete service—including material selection, ordering, delivery, and installation—so you don’t have to find and juggle multiple suppliers.
