Timber Board and Aggregate Steps

Date published: 30 March, 2015

Steps are only to be used in situations where a ramped path cannot reasonably be constructed without exceeding a 1:12 gradient.

Your Woods In and Around Towns Operational Plan and map must detail the length of the steps and provide justification for their installation.

Timber board and aggregate steps:

  • timber board risers fixed in place with half round timber stakes
  • step treads filled with Type 1 granular sub-base
  • surfaced with 10 millimetres of whinstone or granite dust
  • all timber to be treated
  • steps to be level and evenly spaced
  • width of steps to extend 150 millimetres either side of path width
  • height of risers – no more than 150 millimetres
  • tread depth – 500 to 1,000 millimetres
  • tread sub-base – 150 millimetres level and compacted Type 1
  • edges of treads to be dressed of using soil material, compacted, and allowed to seed in naturally
  • paint treads of steps with non-slip surface paint in accordance with manufacturers recommendations
