Tasman concrete block retaining wall system

RETAINING WALL – TASMAN BLOCK

Tasman® block retaining wall systems are designed and manufactured for Australian conditions. The Segmental Retaining Wall Systems (SRWS) are suitable for constructing strong and durable walls for residential and commercial projects.

The split face and natural colourways offer a texture and tone that will complement the Australian landscape and add beauty, value and functionality to your property.

Plus, the Tasman® SRW system has been extensively tested, performing well both in the lab and in the field.

Tasman® block retaining wall systems offer the following benefits:

  • Do-it-yourself quality retaining walls
  • No need for concrete footings
  • Suitable for right-angled corners, steps, straight or curved walls
  • Create near vertical retaining walls
  • Positive connections requiring no pins or plastic connectors.
  • Snug-fitting connections limit movement when correctly installed.

The Tasman® block SRWS is constructed up to 660mm high for straight retaining walls (three courses and one cap) and 860mm for serpentine retaining walls (four courses and one cap).

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

Calculating Block Quantities: Example

  • 20 metres long x 0.9 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 the job = 200 Norfolk Blocks + 52 Norfolk Capping Blocks
