Heaving Pier Foundation

[Exosoldier22]

Hello All,

I have a 2 story barn original to the home(1800s), at some point it looks like the original foundation was pulled and a concrete Pier Foundation was put in. As noted in the pictures they are in very rough shape. Most have heaved completley out of the ground with some being only 2' deep into the ground. I am in Maine and I would be more comfortable with a 3'-3 1/2 concrete Pier with footer. Drainage is also a problem at this part of the home. I am installing a French drain along the perimeter of the entier home this summer. How could I dig new piers under the existing barn without major excavation? I do not really want to pull up the floors but that's starting to look like the only option?

I would say the ones on the outside could be done one at a time after some temp supports are put in between the bad ones. For the inside ones I would cut out sections of the floor for access and then work thru the holes. If the crawl space was greater maybe work from below but it just looks to tight to me.


It will be slow going as a DIY project working alone but could be done.
