I'm building a 3mx3m BBQ shelter. It's a large structure with a roof that will catch the wind like a kite, so I've decided the posts should be buried and concreted for strength rather than attached post holders.
I've got 150mmx150mm pressure treated posts that I'm burying 600mm into the ground.
Question - what can I use to add an extra layer of protection on to the wood before I set it in concrete?
The internet seems to recommend copper based preservatives or old fashioned creosote, both of which I can't find.
Thanks!
