Retaining Wall Builders in Byron Bay, Northern Rivers

It depends on materials, access and design. Natural stone options like sandstone or basalt are more premium than concrete sleepers but last longer and look better over time. 

Generally you can expect to pay between $250 - $950+ per m2 around Byron Bay & Northern Rivers.

This rule says that for every metre of height, you should allow at least a third of that in depth behind the wall for structure and stability. 

So, a 1-metre tall wall should have around 300mm of support or base.

But the land doesn’t always follow neat rules.

Wet clay behaves differently than sandy soil. A gentle slope might let you get away with less, but a steep bank needs more.

That’s why we never treat two sites the same. 

At Gondwana, we read the lay of the land before we make a move. It’s about balance, not just measurement.

A stonemason selects, cuts, and lays stone to create durable and visually striking structures. In Byron Bay, we  work with locally sourced sandstone, basalt, and bush rock to build everything from dry-stacked walls to bespoke garden features. 

We handle everything from site prep and foundation work to fine finishing.

How long do retaining walls last?

With proper construction and drainage, our stone retaining walls can last decades with minimal maintenance.

Absolutely. 

We design each wall to complement your home’s architecture, plant palette, and outdoor layout.

Yes. We regularly collaborate on construction projects across Byron Bay and Northern Rivers.

If we’re talking bang-for-buck, treated pine sleeper walls are usually your most affordable option. 

They’re like the corrugated tin of landscaping – practical, honest, and they get the job done.

At Gondwana, though, we don’t just chase cheap. 

We look at the full picture – your soil, the slope, the lifespan you’re after. 

Because a retaining wall isn’t just holding back dirt, it’s shaping your entire garden’s story. 

Sometimes a budget-friendly timber wall makes perfect sense. Other times, spending a little more on local stone gives you decades of low-maintenance.

This list comes up a lot. 

We see it often – well-meaning DIY jobs or rushed builds that overlook the basics.

 Here are the seven usual suspects:

1. No proper drainage – Water builds up behind the wall like pressure in a blocked pipe. Eventually, something’s got to give.
2. Shallow footing – Think of it like building a house on sand. A wall is only as good as what it’s standing on.
3. Wrong materials for the site – Using concrete blocks where natural stone suits better, or vice versa.
4. Poor backfill – The soil behind the wall should let water pass through, not pack tight like a dam.
5. Lack of reinforcement – Especially for taller walls, strength matters. We might use geogrid, deadmen or solid core fill depending on the build.
6. Ignoring expansion gaps – Materials move over time. Without space to flex, things crack.
7. Short-term thinking – A quick fix now often becomes a costly rebuild later.

At Gondwana, we think long-term. Every choice is intentional, from the footing depth to the stone we lay by hand.
