Platform supports settling

[Montanafront2012]

Good Afternoon,

I have had a 24 ft Yurt in Northern Vt since 2013. This Spring I have experienced some settling of the platform support posts into the ground.

The platform is supported by 4X4's sitting on poured concrete grade level bases. I did not have a level with me but I guessing the settle was 3-4 inches. (see attached pictures, the picture of the yurt itself is from years ago so you can see the terrain)

I am not sure why this happened after 7 years. The land to the south and west is higher elevation so I believe this is caused by moisture/freeze-thaw.

I was thinking that I would rent/buy a jack, jack up the platform post by post, then replace with a longer 4X4 post to account for the settle.

Any thoughts on this subject would be greatly appreciated.

If I can get the platform back to level I need to think about a way to keep

moisture

away from the area containing the supports.

Best Regards,
