8' Fence Problems - Leaning after Storms

We have an 8' fence (we live on a main highway with lower land). See picture below. We had a real high wind gust and heavy rain hit on Sunday and it caused the posts pictured to shift in the ground. This happened last year when a Cat 1 hurricane passed through as well. At the time, I got the fence company to come back out and reinforce the post with more concrete mix. Obviously , that didn't correct the issue. This happens in our low spots where the water drains off our land.... the ground gets so saturated right there that this could be an ongoing issue. We built on natural "wetlands".

Any suggestions? Pic below is an example of what I am talking about. Our situation is a little worse than this.

I think you need to apply force with stakes in ground to straighten it out then reset the post or buy these below lol

My concern with those stakes is that they don't go deep enough into the ground. I feel like with the soil conditions , it will still shift with the post. I thought about driving 12' sticks of 2" galvanized pipe about 4' into the ground and anchoring those to the fence with some u-clamps.

Some missing details in your post (no pun intended). Is this a new fence? Wood? Post size? Shadowbox? Are posts bending or is the ground giving away?

If wood and ground is giving way, there might be a materials savings cost of not using long enough posts and/or not close enough spacing of posts. If wood and the post is also bending, going up to 6x6 post will help.

I would pull/jack the old posts plumb or pull completely and replace. A lot more concrete will be required. Then I would add posts in problem areas. If your posts are 8' apart, add so they are 4' apart. This spreads out the force to the ground.

I have a problem 6ft fence that is in an area always wet. Going from 8ft spacing to 4ft spacing solved my issue. I also throw in a temporary brace for named storms I know are coming.

It's 4 x 4 wood posts spaced every 8'. The ground is giving way mainly. Post seem to still be straight for the most part. The fence is not even 2 years old. So you would recommend placing more 4 x 4 post in between each 8' run? And maybe add more concrete to the already existing posts?

Any thoughts on using galvanized pipe instead of 4 x 4 wooden post?

The posts were not buried deep enough for the soil. I wouldn’t normally recommend this, but I would probably try some of that expanding foam made for setting fence posts.

You will need to pull each post past vertical, and then fill the gap with foam (or whatever you choose to use).

How long are the posts? How deep are they below grade?

I'm assuming they are 10' post and about 2' or so in the ground. I think they needed to be 3' or more minimum with that soft ground. I may try and add more 4 x 4 post in between the runs and make sure those are 3' in the ground with 80lb bags of concrete per post..

Should’ve used 6x6 post 3’ deep, not enough post to hold up the weight.
Going to be a PIA but split difference and use 6x6.

There is a huge difference an 8' fence vs a 6'. Everything needs to be twice as robust for that extra 2'

That is your problem. 1/3 of the post should be in the ground is the rule of thumb.

I used 4x6x12 posts cemented 4' in the ground with 5 lats and 1x6x8 boards as pickets with 2 layers of ReadySeal

One side of my fence was 8 feet before Ida. Put 6 ft after Ida. The guy who rebuilt it put all 4x6. 3 ft deep, cut a foot off the top, and 100lbs of premixed cement per post. It’s solid as a rock. I’d recommend adding at least 4x6 3 or 4 ft deep.
