Tanalised timber used to be quite specifically “CCA” (Copper Chrome
Arsenate) in a water borne process, originally developed at the Forest
Research Institute in Dehra Dun, India. Its great property is that it
chemically combines with the hydroxyl groups on the timber and cannot,
therefore, be leached out by ponding or wicking when subjected to
passing water and fights the tendency of mycelial sacrificial hyphae
to translocate away from the hyphal front the heavy metal ions that do
the protection.

Chris, please, please, please find the time to add your knowledge of timber
preservation to the group Wiki thingy (John Rumm knows what I mean).
