I've been asked to replace a wooden gatepost (95mm) that is placed directly next to a concrete post.

The wooden post supports quite a heavy wooden gate and has broken at the bottom where it rotted.

I'm planning to dig out the rotten wooden "root" of the post and put another one in but use the concrete post to strengthen it by putting some metal plates on.

It occurred to me to wonder whether the kind of resin used for resin fixings would be any good as an adhesive in this situation - perhaps inspired by the way silicon sealant can act as a very effective adhesive when used on a shower screen!
