Retaining Walls
Retaining Walls Brisbane | Urban Earth & Civil
Concrete sleeper and sandstone block retaining walls supplied and installed across Brisbane and South East Queensland. Built to handle sloping sites, erosion control, and access challenges on residential and commercial projects.
What we deliver
Retaining walls are essential on sloping sites, boundary transitions, and anywhere you need to manage ground levels. We supply and install concrete sleeper and sandstone block walls that are built to last and engineered to perform.
Every wall we build starts with proper planning — understanding the soil conditions, drainage requirements, and load expectations. We work with engineers where required to make sure the design is right for the site.
From small residential boundary walls to larger structural retaining systems on development sites, we deliver clean, professional results with attention to finish and long-term performance.

Frequently asked questions
Do I need an engineer for my retaining wall?
In Queensland, walls over 1 metre in height generally require engineering design. We coordinate with structural engineers and can arrange this as part of the project.
What types of retaining walls do you install?
We install concrete sleeper walls (galvanised steel posts with precast sleepers) and sandstone block walls. Both are durable, cost-effective options suited to Brisbane conditions.
What does a retaining wall cost?
Retaining wall pricing depends on the height, length, material type, soil conditions, and site access. We provide detailed quotes after reviewing your site. Contact us with your details and we'll come back to you quickly.
How long does a retaining wall take to build?
Most residential retaining walls are completed in 2–5 days depending on length, height, and site access. We'll give you a clear timeframe when we quote.
Do you handle drainage behind the wall?
Yes — proper drainage behind retaining walls is critical. We install ag-pipe and drainage aggregate as part of every wall build to prevent water pressure build-up.
Can you build retaining walls on steep blocks?
Yes. Steep and sloping blocks are our speciality. We regularly build multi-level terraced retaining systems and structural walls on challenging sites across Brisbane and SEQ.
