Problem:
Two piers, located side-by-side on two separate floor joists have sunk, resulting in their detachment from their floor joists. The floor joists are still supported by the remaining piers, but the detachment has caused some sloping in the floor. I am not necessarily looking to straighten the floors, but my main goal is to make sure that the floor is structurally supported as originally designed. By the way, it appears that the floor joists sunk due to water getting under the house and pooling at one spot.

My Question:
How is something like this fixed? A concrete contractor bid the job as 1) removing old piers and 2) installing the new ones with RV jacks installed in concrete. The concrete footing would be 1 foot deep. It seemed like that would work, but I'm afraid a building inspector would look at the jack stands and say "unacceptable".

Thanks, in advance, for the valuable advice.

How tall and wide are these piers?
The R.V. jacks are a no no. If any jacks are put there is mist be rated house posts Adjustable or not. The moisture is a problem with steel being exposed to the elements. I would be curious of what footer system is under thoses that sunk.

Where I come from a contractor would never suggest R.V. jacks.

How much house is above the piers?

It may be possible to side pin the piers with a wider footer to carry the load. A bigger foot print so to speak. If what's there now sunk how much bigger will the new footers be in width? What's your Geo for temperature changes in difference's?

There is a bit more going on here than a footer sinking if the pier Detached from the joist. They keep sinking on there own weight. Its not like the house weight kept pressure on them and the ground was soft. What the water runoff and drainage there by the piers. That's what needs explored here before the "Fix" Or the problem may arise again.
