I live in a 2.5 year old home with an unfinished basement. Part of the basement is below grade on one end and walk-out on the other. I have had no water problems and no moisture problems to my knowledge. I plan on finishing the basement and wonder if I need to paint the walls with Dryloc and seal the floors before carpet is laid? The basement was wrapped when new, but I do not know if this is a sure safeguard. Any comments would be appreciated.
