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
