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. We stock Spescoat deep treat and True Blue log end sealer.
  • Time of year of installation for best result
  • The most stable maximum size we recommended for posts is 150x150.
  • Diggers Eco In-Ground Timber Protecta is a non hazardous ‘creosote alternative’ that provides a tough bitumen coating to improve protection against moisture and deterioration on timber and masonry surfaces. … Diggers Eco In-Ground Timber Protecta is perfect for things such as: Fences, veranda posts and sleepers.
