How to calculate a sheet size for a single span tunnel:
  • Determine the width (a) of the tunnel and the length (b)
  • Use the table below to select the correct width of sheet
  • If the table is inconclusive measure the over hoop (c) and add on extra for fixing method. 2m extra for trenching, 1m for timber batten fixing and 0.75m for grip rail
  • To determine length of sheet needed add length (b) to width (a). Add extra if doors need to be recovered
