Hello I am new to the forum and new to home ownership and need some advise.
We have been having continous issues with our mudroom frost heaving in the winter, to the point of not being able to open and close our door. The room was built on and has no foundation; under the room is (clay mix) dirt and held up by what I call car jacks, but a little bigger. We did a french drain, and added plastic and gravel in the front of the room moving the water away from the house, which did work for 1 year. But this year with the below freezing temperatures it's beginning to heave again. The door won't lock, cracks are appearing in the drywall and our new floor has a 1" bludge in the corner from what I think is the jack pushing up.
Any thoughts advise would be welcome.
Also I have pictures of the cracks to give a better idea of what it's doing.
