FAQs

Do I need council approval for a retaining wall?

1

Generally no permit is needed for walls under 1m on flat ground that aren't near a boundary or easement. Walls over 1m, close to a boundary, or supporting a structure usually need assessment. Rules vary by council — Brisbane, Logan, Redlands and Moreton Bay each have slightly different requirements. We'll flag anything during the site visit.

Timber or concrete sleepers — which should I choose?

2

Timber is the most common and cost-effective choice for most Brisbane residential walls. Concrete is better for taller walls (over 1.2m), sites with significant soil pressure, or where a longer lifespan is the priority. We'll recommend the right product for your site during the quote.

How long does a retaining wall last?

3

A well-built hardwood sleeper wall with proper drainage should last 15–25 years in SEQ's climate. Concrete sleepers last 30+ years. Rock walls are essentially permanent. The biggest factor in lifespan is drainage — a wall without proper ag pipe drainage will fail significantly earlier.

How long does the job take?

4

A standard 8–10m residential wall typically takes 1–2 days. Larger jobs, difficult access, or combination wall-and-fence jobs take longer. We'll give you a realistic timeframe when we quote.
