A recent deck replacement on my circa 1890 home has led to me discovering some worrisome foundation issues. Even ostensibly simple jobs on my home lead to the peeling of this 100 year old onion and revealing bigger problems. The challenge is always to do “just enough” as I expect when my family and I move on this home will be torn down, like all my neighbours homes slowly are 😥. 

The section of my home in question is part of an addition put on around 1940. The basement walls looks like they were poured in horizontal lifts. Nothing I’ve ever seen before myself. I removed the old deck ledger and found a rotten beam without a capillary break. Then I removed the siding installed over the basement wall out wall and found some significant cracks in the foundation. The footing lacks insulation and is only 16” below grade, so I assume frost heave is the culprit. im going to add insulation and frost protection, but my main question is regarding the cracks. I’m hoping, given how long it’s stood here so far, and given the situation doesn’t seem to be worsening (a cement repair likely at least 20 years old and hidden by the now removed siding seems to be in tact) I can fill the cracks, insulate the wall, and go back to the manageable, baseline level of anxiety about my old home’s many issues I’ve lived with for the last 10 years. 

I’m thinking epoxy repair. Any thoughts, recommendations would be appreciated.
