Norfolk concrete block retaining wall system


Norfolk® block retaining wall systems are designed and manufactured in Australia for local conditions. The Segmental Retaining Wall Systems (SRWS) are suitable for constructing strong, durable aesthetically pleasing walls for commercial and residential projects.

With split face rock textures and natural tones, Norfolk® blocks will enhance your landscaping and add value and usability to your property.

The Norfolk® SRW system has been extensively tested in the lab and in the field.

Norfolk® block retaining wall systems offer the following benefits:
• Do-it-yourself economical retaining walls
• No mortar required
• Structurally sound
• Low maintenance

The maximum height permitted for straight and serpentine Norfolk® block retaining walls is 900mm (four blocks at 180mm plus one capping block at 180mm).

If you are intending to use Norfolk® block retaining walls to support higher embankments please seek the advice of a competent civil or structural engineer; walls must comply with the Australian Standard AS4678 Earth Retaining Structures.

It is the owner’s responsibility to determine if council approval is required for retaining walls, regardless of the wall height or site conditions.

Check with your local council to ensure compliance with all local building codes.

Calculating Block Quantities: Example

  • 20 metres long x .9 metres high = 18m2 x 14 blocks per m2 = 252
  • Less 20 lineal metres x 2.56 capping blocks per metre = 52 capping blocks required overall
  • Blocks required for complete job = 200 Norfolk Blocks + 52 Norfolk Capping Blocks


Retaining Wall Designer

Our Retaining Wall Designer is a free online tool for creating engineering designs for retaining walls using our Tasman® and Norfolk® blocks.  The tool has two operating modes Basic and Pro.  Use the tool to design reinforced cantilever, segmental gravity and segmental reinforced soils retaining walls.
