We recently had a new deck put out back. They dug post-holes about 8 feet deep for it. While the holes were there, we had some rain and 2 of the holes collapsed, with dirt falling away from the house and exposing some of the foundation. They filled them in and completed the deck. I'm not sure exactly how well they filled them; it looks like there has been a little bit of subsidence, but it is small compared to the size that the holes were.
Shortly after it was built, we had a leak in the basement wall during a rain. It's a small one, just enough to soak a couple bath towels during a big storm. It's along the back wall, but some distance away from where they were digging. Later, a smaller one appeared closer to where they were digging.
We hadn't ever had the basement leak, for almost 30 years. Is it possible the post-holes had something to do with it? Now, one relevant thing is that the gutters in the back fell down a few years ago, so there aren't any there right now. I'm sure that's a contributing factor, but there were no actual leaks until just after they did this work.
The other day during Hanna, we also had a tiny leak toward the front. There are gutters up there, in decent condition and clean. Incidentally, they also dug a few post-holes for some handrails out front, near where this third leak has started. (There were no problems with those holes collapsing.)
We have a sump pit in the basement, but it was dry, at least after the first two leaks started. There is no sump pump in it, as we've never found water there.
What is the likely cause of these leaks? (Besides the obvious that we need gutters in the back?) Also, what's the best thing for patching these leaks?
