I hope you'll update us on how it works. We have a trouble area near our Bilco door. Hubby did some drainage work but it's not working as well as he'd hoped, and I think we'll need to do something more aggressive.
Seems to be ok so far. Funny you should mention it, my other trouble spot is the Bilco door. Seems to be coming in through the side wall. Another project for another time ( As Cubs fans say, there’s always next year).
