Why Customers Choose BlockCon Retaining Walls

Frequently Asked Questions

How tall can my retaining wall be?

In most areas, retaining walls up to 600mm high don’t require council approval. Anything taller generally needs engineering and council approval, especially if it’s close to a boundary or supporting additional weight. It’s always best to check with your local council to confirm what applies to your property.

Can I install a retaining wall on a slope?

Yes, retaining walls can be built on sloped or uneven ground. In fact, they’re often used to stabilise slopes and prevent soil erosion. Depending on the gradient, the wall may need to be stepped or built in tiers to follow the natural shape of the land. Proper design, drainage, and engineering are essential, especially on steeper sites to ensure long-term strength, safety, and compliance with local council requirements.

Are your retaining walls engineered for strength?

Absolutely. For taller or load-bearing retaining walls, our team partners with licensed engineers to guarantee long-term strength and full compliance with council standards.

Does my neighbour have to pay for the retaining wall?

If a boundary wall helps both properties, costs are generally split between neighbours. If it’s on your land or only for your property, you’ll usually pay for it yourself. Always check with your council for local rules.

How long does it take to build a retaining wall?

Most retaining wall projects take between 2 and 5 days, depending on size and complexity. We’ll provide a clear timeline before starting and keep you informed throughout the process.
