Did you forget something?
We often think that a concrete structure is sound and has no need for termite protection, but unfortunately, the very formwork used to create these concrete creations are the cause of termite problems.

Alhough this building did not have timber structural elements, it had a lot,of decorative timbers inside that were damaged. Just because it's not structural timber doesn't mean the termites won't eat it, and some decorative timbers are not cheap to replace.
An eradication programme ridded this building of termites and the owners were informed to remove all formwork to prevent this happening again.
