Had a nice little foundation leak during the last rain storm. Installed a drain line last fall to divert two downspouts and front walkway run off away from the house which helped a lot. Front walkway and a big retaining wall next to it ultimately need to be removed and reinstalled with proper grading and drainage. That’s going to be a huge and expensive project so for now I’m just replacing all the worn out concrete sealant and hoping for the best.
That’s not a basement problem, that’s a location problem. Look for houses that are higher up than other houses, the water will flow down the hill and flood the people who didn’t do that.
Very often there just isn’t a “higher up.” Much easier, and especially easier on the mind, to not have a basement. At least for me.
So then your base floor floods
No.
