You can do the drylok, and then the new owners can be screwed. Guess what is peeling off my basement walls as I struggle to come up with the money, patience and time to deal with our basement water problem? Oh; you guessed it - Drylok! With the bitter new homeowner in me out of the way....I have an older house ,built in 72, and during heavy rain the basement leaks. We are in the process of selling the home and the basement poses concern to future buyers. It's not a finished basement, and using a dehumidifier it dry's in less than a day. I've heard pro's and con's with using drylok and just don't know what to do. We have had estimates on waterproofing and most say do a french drain, but the cost is so much. Any suggestions would be greatly appreciated as we thought about applying the drylok soon. Thanks
I suggest you disclose the problem regardless of how you fix it, and provide the paperwork on how you had it fixed. Drylok isn't a fix in my eyes, it is a cover-up. Since you have just light moisture; You could assess the grading and gutters and fix any deficiencies there; which may alleviate the problem or in some cases eliminate it. If there is a gutter leaking bad or absent; or a portion of the house has bad grading; that water could be collecting around the foundation.
Sorry you have water in the basement; it really makes you pull your hair out...
EDIT: I believe it is called "inward drying"; as the foundation gets wet it needs to dry inwards, drylok locks the water in the foundation. Here is a great read:
