Common Questions
Frequently Asked Questions
Do retaining walls need engineering certification in Adelaide?
In most Adelaide councils, retaining walls over 1 metre in height require engineering certification and a development application. Marvel Concrete works with qualified structural engineers to ensure all designs are certified and council-compliant.
What height can a concrete retaining wall be?
Concrete retaining walls can be built to significant heights with proper engineering. Walls under 1 metre typically do not require council approval, while taller walls need engineering design, certification, and council approval. We design stepped or tiered walls for very tall embankments.
How long does a concrete retaining wall last?
A properly engineered and constructed concrete retaining wall can last 50+ years with minimal maintenance. Concrete is one of the most durable materials for retaining walls, resisting rot, termites, and weathering far better than timber alternatives.
Can retaining walls be decorative as well as structural?
Yes. Marvel Concrete offers a range of finishes for retaining walls including exposed aggregate, smooth rendered, and textured finishes. We can also integrate garden beds, seating, and lighting into retaining wall designs to create functional and attractive outdoor spaces.
