Treatment specification
Treatment specification
(OP)
Hello,
Copper arsenates are no longer being allowed. So, what is appropriate timber treatment for bridges over waterways? Is creosote allowed at all?
My understanding is that creosote has been replaced by the various copper compounds. But isn't copper harmful to aquatic environments? And why is copper so harmful to aquatic environs. What have you been specifying, the last project we did we used ACQ, should I stick with this? I really don't feel like I have the time or the budget to justify extensive research into the latest environmental documents, so any input is much appreciated. Thanks.
