Premium AS3600 certified concrete sleepers and galvanised steel posts. Delivered direct to sites across Greater Sydney, from the Western Suburbs to the Northern Beaches.
Before you start digging, it is crucial to understand local building codes. In the Greater Sydney area, you can generally build a retaining wall without council approval (as Exempt Development) provided it meets these strict criteria:
Walls exceeding these limits generally require a Development Application (DA) or Complying Development Certificate (CDC) and a Structural Engineer’s certification. All of our concrete sleepers are AS3600 certified to satisfy NSW engineering requirements.
Disclaimer: Regulations vary between local councils (e.g., Blacktown, Hornsby, Sutherland Shire). Always consult your local council before commencing any structural work.

In New South Wales, retaining walls generally require local council approval if they exceed 600mm to 1000mm in height, or if they are built close to property boundaries. Regulations vary significantly between councils (e.g., Blacktown vs. Sutherland Shire). Our structural walls over 1000mm require standard engineering sign-off.
Yes. Our retaining wall steel posts (both H-Beams and C-Channels) are hot-dipped galvanised to AS/NZS 4680 standards. This provides maximum protection against rust and corrosion, making them ideal for high-salt coastal areas like Sydney's Eastern Suburbs and Northern Beaches.
