Post Species choice – Design Factors to consider when specifying-

  • Grade- visual grade or structural rating or both.
  • Durability- above ground (a/g) and or in ground (i/g). see- design guide 05
  • Stability – normally the lower the radial shrinkage, the lower the propensity to twist and crack.
  • Moisture content required(m.c.) will depend on the purpose/ use.
  • Acclimatizing coatings- penetrants and end sealers.
  • Time of year of installation for best result
