Help - Termites in my stack of TanE treated hardwood
I have a stack of TanE treated hardwood sleepers that has been sitting around for say 12 months. The other day I decided to use some and as I was unstacking them I noticed that the termites were living between the boards and had eaten some grooves into a few of them.
I have been using the sleepers to build a retaining wall and now seriously wonder if they are going to eventually become termite food.
The sleepers are a mixture of spotted gum and ironbark.
I mentioned about the termites, over the counter, to one of the sales people who sold them to me and he was fairly nonchalant about the whole matter saying words to the effect that the chemical treatment really only goes into the sapwood.
Was I misguided to believe that these sleepers were termite proof?
What should I do?

Kidbee, I believe that hardwoods are hard to treat properly because of the penetration difficulty..so the person who sold it to you was probably correct. I am sure that someone told me some time ago that the termite treatment does go deeper into the softwoods.
The hardwood will become termite food. I had a treated hardwood sleeper completely hollowed out by termites so I got the whole house treated.
It's 6 of 1...half a dozen of the other. The treated pine will by more termite resilient but not as strong in the retaining wall or wood rot resistant and would need shorter spans between the posts.
The hardwood is stronger initially, take the moisture better but if you have termites nearby and they get eaten out...they become weaker of course.
You may have to do the retaining wall in more termite resistant softwood sleepers with plenty of gravel behind it to take away the moisture quickly.

Termites must be hungry at your place. They will normally eat anything else but hardwoods. Only moving onto them after they have eaten all the softer options.
