Deck Concrete Footing

I recently removed my pool. I have a deck right next to my pool. I have to add some topsoil where there pool was, which the increase the ground height around the deck footing. The ground height will be higher than the concrete section of the footing and will cause part of the wood post to be underground.

What can it do to prevent the wood post to rotting underground?

Can I use a rubberized undercoating to protect the wood? If so, what kind?
Should I extend the height of the concrete footing, if so how?
Any other options?

Thanks in advance for the assistance.

Suppose you wrapped a sonotube around it & filled it with gravel? That would keep the dirt away & let the water drain. It's also the cheapest option.

Thanks for the suggestion, I might most likely do that. If I were to do it the "right what" what would it be. Can I just increase the height of the existing footing?

What is the "right what"? Did you mean the "right way"? There is no reason to increase the height of the footing. There is no reason to touch the footing, at all. Gravel in a sono tube, will keep the dirt away, with the least amount of work & cost.

It won't degrade any faster than we will.

Sonotubes are designed and constructed to be used as temporary forms for holding concrete. If filled with gravel instead of concrete, they will degrade over time, and under moist conditions won't last more than a few years. I'd extend the footing with concrete, so you won't be going through the gravel/sonotube routine again.

If he extends the footings, he has to shorten the posts. Otherwise he will be back to square 1 with the wood absorbing moisture, from the concrete. If sono tubes are no good, there must be something else that can be used to hold the gravel.

Did I miss something? Can't the columns be shortened, using a saw?

There has to be an easier way protect the wood, from the moisture. If sono tubes won't last, I would use dry wells to hold the gravel.
