We all call it but do you have stats?

I am referring to earth / ground contact and Earth / concrete contact vs having posts for porches and decks on a footing with a metal bracket mount.

How long for post base rot if in contact with concrete vs earth for instance.

Bonus question:
Do you call out posts for small decks placed in those precast concrete footers?

Do actual stats exist ?

Doubtful.

We have an actual construction standard for decay protection. Protection against decay and termites.

To answer your question of how long it will take to rot. That would be a question the same as, when will we die.

When I see mushrooms growing on the post, haha, I call it out.

Bob you raise a good question.
