I have a 125+ year old house with a fieldstone and poured concrete basement. There are a couple old pipes coming through the basement wall I would assume are from an old well that was filled in 75 years ago. When we have a big snow melt or a good rain the pipes drip water (I would assume the pipe are rotted in the ground or maybe even cut off).
The previous owner stuffed plastic bags in the pipe as shown in the image but that certainly does not solve the problem! Digging up outside by the wall is not an option and for 1 pipe there is not enough lip to put a cap on.
Can I use a spray foam to fill these in and expect it to be watertight?
Any other suggestions?
