Hi, M. Until you fix your drainage problem, you will not be able to fix your walls. There are many post down the board about water problems in basements and crawl spaces. You can search, but it's probably just as easy to scan down. You have to get all water flowing away from your basement walls. When you have accomplished that, most of your problems should go away. And no matter what you do to your walls from the inside, you will continue to have problems if you have water coming in from the outside.
