I have 2 story home on an old deteriorating block foundation. It leaks like an open faucet whenn it rains heavy. I understand the process of jacking the house up 6"+ to replace it, and with that face losing my front porch, my deck on the back, and possibly cracking walls and ceilings on first and/or second floors. My question, is it possible to excavate the entire foundation and fill the blocks on the exterior with concrete and patch it? I know I can have walls poured inside the foundation in the basement to structurally support it, as an alternative. But that wont stop the water from coming in and I will eventually lose my basement that way. Just looking for advice options. Any help is appreciated.
