How much does a retaining wall cost in Brisbane?
Retaining wall costs in Brisbane vary depending on the wall type, height, length, and site conditions. Timber sleeper walls typically range from $250-$450 per lineal metre, block walls from $350-$600 per lineal metre, and concrete walls from $500-$1000+ per lineal metre. We provide free on-site quotes to give you an accurate price for your specific project.
Do I need council approval for a retaining wall in Brisbane?
In Brisbane, retaining walls over 1 metre in height generally require council approval and engineering certification. Walls under 1 metre typically don't require approval unless they're near boundaries, support surcharge loads, or are in flood-prone areas. We can advise on approval requirements for your specific situation and handle the application process.
What type of retaining wall is best for my property?
The best retaining wall type depends on your specific needs. Timber sleeper walls are ideal for garden beds and lower walls with a natural look. Block walls suit medium-height walls and offer various aesthetic options. Concrete walls are best for high walls, heavy loads, and commercial applications. We'll assess your site and recommend the most suitable option.
How long does it take to build a retaining wall?
Build times vary based on wall size and complexity. A small timber sleeper wall (5-10m) typically takes 1-2 days. Medium block walls take 3-5 days. Large concrete walls may take 1-2 weeks including curing time. We'll provide a timeline estimate with your quote.
How long do retaining walls last?
Lifespan depends on the wall type and materials. Treated timber sleeper walls last 15-25 years. Hardwood sleeper walls can last 25-40 years. Block retaining walls typically last 30-50 years. Concrete walls can last 50-100+ years with proper construction and drainage.
Do retaining walls need drainage?
Yes, proper drainage is essential for all retaining walls. Without adequate drainage, water pressure builds up behind the wall, causing failure. We install agricultural drainage pipes and gravel backfill on all our walls to ensure water drains away effectively.
Can you build a retaining wall on a boundary?
Yes, but boundary walls have specific requirements. You may need neighbour consent, and the wall must comply with boundary setback rules. Walls on boundaries often require engineering certification regardless of height. We can advise on the requirements for your situation.
What is the maximum height for a retaining wall?
There's no absolute maximum height, but walls over 1 metre require engineering design and council approval. Very high walls may need to be built as stepped/terraced walls or require significant engineering. We can design solutions for any height requirement.
Do you offer warranties on retaining walls?
Yes, all our retaining walls come with a structural warranty. The warranty period varies by wall type - typically 5-10 years for timber walls and 10-20 years for block and concrete walls. We also provide workmanship guarantees on all projects.
