Rotting joints to main supports of the pergola:

  • Although the rotting timber to this junction of the main supporting beams had been reinforced, it has not been constructed correctly.
  • The post must be located directly below junction of the main beams.
  • The main support beams should have been checked into the post, so as not to rely solely on bolts that will rust.
  • A checkout creates a shoulder for the beams to rest upon even when the bolts rust they will still be supported.

Important points:

Open timber structures serve no practical purpose when they have no roof sheeting attached over them for protection. Shade-cloth allows for very little protection and traps moisture that accelerates rotting of the timber.
