What Affects Retaining Wall Costs in Sunshine Coast

Wall material

Timber sleepers ($195–$435/lm in Sunshine Coast) are cheapest. Concrete sleepers ($240–$580/lm) are the most popular. Sandstone ($340–$680/lm) is premium but looks great.

Wall height

Walls under 1m are straightforward. Walls over 1m in Sunshine Coast typically need stronger footings. Over 1.5m requires structural engineering certification.

Engineering requirements

Walls over 600mm (some Sunshine Coast councils) or 1m (others) need a structural engineer's design ($485–$1,950). This adds cost but is legally required and protects you.

Drainage

Every retaining wall needs drainage behind it ($29–$78/lm in Sunshine Coast). Without proper drainage, water pressure builds up and the wall can fail within a few years.

Site access

Easy access for a small excavator in your Sunshine Coast property keeps costs low. If materials need to be carried by hand (steep slopes, narrow access), costs increase significantly.

Existing wall removal

Demolishing and removing an old failed wall in Sunshine Coast costs $50–$180/lm on top of the new wall cost.

Frequently Asked Questions

How much does a retaining wall cost per metre in Sunshine Coast?
A retaining wall in Sunshine Coast costs $195–$435/lm for timber sleepers, $240–$580/lm for concrete sleepers, and $340–$680/lm for sandstone (all at approximately 1m height including footings).
How much does a 10m retaining wall cost in Sunshine Coast?
A 10-metre retaining wall at 1m height costs $2,425–$6,800 in Sunshine Coast, depending on the material chosen, site conditions, and drainage requirements.
Do I need council approval for a retaining wall?
In most Sunshine Coast councils, walls over 600mm–1m require a development application. Walls over 1.5m almost always need engineering certification and council approval. Always check with your local council first.
What's the best material for a retaining wall?
Concrete sleepers offer the best value — they're durable, low-maintenance, and look good. They cost $240–$580/lm in Sunshine Coast. Timber is cheapest but has a shorter lifespan (15–20 years vs 50+ for concrete).
How long does a retaining wall last?
Timber sleeper walls last 15–25 years. Concrete sleeper and block walls last 50+ years. Sandstone and boulder walls can last indefinitely with proper drainage. The biggest factor is drainage — poor drainage is the #1 cause of wall failure.
Can I build a retaining wall myself?
Small walls under 600mm are a feasible DIY project. Anything taller in Sunshine Coast should be done by a professional — the weight of retained earth is enormous and failure can damage property or cause injury.
