A dedicated retaining division building every wall system — with structural integrity and proper drainage built in.
Our Specialty
Retaining walls built to last
Retaining walls provide structural integrity to your home and should be looked at as an investment. Each particular system has its own suitability. We offer you professional advice on which system best suits your requirements. Designer Image specialises in all types of retaining and have dedicated teams for each type.
Our retaining division holds the QBCC Builders licence required to complete structural retaining walls outside general landscaping specifications, and works closely with RPEQ certified engineers and licensed certifiers to ensure compliance with local authorities.
We build concrete sleeper walls, besser block walls, rock and boulder walls, dry stack block walls and timber sleeper retaining walls. Each system has its own suitability depending on wall height, soil conditions, drainage, the look you’re after and budget. We have dedicated teams for each type, and we’ll give you professional advice on which system best suits your site rather than pushing a one-size-fits-all solution.
Do I need engineering or council approval for a retaining wall?
It depends on the height of the wall and your local council’s requirements. Taller and structural walls generally need engineering and certification. Our retaining division holds a QBCC Builders licence required to complete structural retaining walls outside general landscaping specifications, and we work closely with RPEQ certified engineers and licensed certifiers to ensure compliance with local authorities. We’ll let you know what your project needs before work begins.
How is a retaining wall quoted?
We quote retaining walls after assessing the site, because cost is driven by the wall height and length, the system chosen, soil and slope conditions, drainage requirements and access for machinery. A retaining wall should be looked at as an investment in the structural integrity of your property, so the quote sets out the scope clearly. We provide an obligation-free quote once we’ve seen the site.
How long does it take to build a retaining wall?
A straightforward residential retaining wall can often be completed within several days, while larger or structural walls that need earthworks, engineering and drainage take longer. Access and weather also play a part. Once our retaining team has assessed your site we’ll give you a clear timeframe and explain the sequence of works so you know what to expect.
Why is drainage important behind a retaining wall?
Drainage is one of the most important factors in a retaining wall lasting the test of time. Without proper drainage, water builds up behind the wall and adds significant pressure that the structure was not designed to hold. Our retaining teams build in appropriate drainage as part of the construction so the finished wall stays structurally sound for the long term — it’s not an optional extra.
Can a retaining wall be combined with fencing or landscaping?
Yes, and it often makes sense to. Many of our retaining projects are completed alongside fencing, garden installation, turf or paving so the finished result is cohesive. Because Designer Image handles both retaining and full landscaping in-house, the levels, drainage and finishes are all planned together rather than being handed between separate contractors.
Which areas do you build retaining walls in?
Our retaining teams work across the greater Brisbane area and South East Queensland, from the Sunshine Coast to the Gold Coast, operating from our central office in Alderley. If you’d like to confirm we cover your suburb for a retaining project, contact us and we’ll let you know.
How tall can a retaining wall be?
Wall height is determined by the site, the chosen system and engineering requirements rather than a fixed limit. Lower walls are often achievable as a landscaping element, while taller structural walls require engineering, certification and the appropriate building licence — which our retaining division holds. When we assess your site we’ll advise the most suitable height and system for what you need to achieve.
