We had 5" of rain, and near one corner of my house with all in-ground
basement, there is a window with outside window well, with stones at the
bottom. Just to the left of the edge of the window well in the basement is a
penetration into the basement of the lines from the outdoor A/C. Just under
that there was a little seepage, which ran in a vertical line a couple of
feet down the basement wall, then stopped. The basement wall is poured
What is the best approach to prevent a recurrence? Should I cover the
window well with a plastic bubble cover? I have an oil tank in the basement
and the lines for the oil are too close to the window well to install a
standard plastic bubble, and I also have an electric line to attach a
gas-powered generator to an electric panel in the basement, that also blocks
a standard plastic window bubble cover.
What about caulk under the A/C line penetration in the basement, or dry-lok
paint? Any other ideas?
Finally, what does it mean that the wet area on the basement wall still is
visible days after the rain stopped?
