Retaining walls can be constructed from a range of materials including timber sleepers poles or posts. These can be used as an effective barrier to construct steps, garden beds and terraced retaining walls on sloped properties. Retaining walls are also an effective remedy for halting the progress of erosion. An important consideration when constructing any retaining wall is the installation of adequate drainage, to prevent water and moisture build up on the retaining structure. This can cause rot and may lead to the collapse of the wall completely.

Timber retaining wall considerations

If you are planning a retaining wall on your property, consider the following prior to construction:

  • timber retaining walls above a certain height will require building approval
  • Australian Standard AS 4678 pertaining to earth-retaining structures should be consulted
  • identify soil type before construction begins and plan accordingly
  • the height of your retaining wall
