Here's my problem and forgive me if the lingo is wrong. Our home is over 100 years old, it doesn't have typical framing. The corners of the house have what appear to be something like 6x6 beams running the entire height of the house. I have one that has rotted at the bottom (no foundation) which was sitting on what I call the plate' which was sitting on some rocks which were cemented in to form a footing. My question is... how can i lift this corner while I pour new footers and replace the damaged section as well. My main question is how can I repair this upright?
