My 55 year old home does not take any water in through the walls during heavy rain, but I do notice small reoccuring wet spots on the carpet in the finished half. I've never seen standing water, only slightly damp carpet. The other half is unfinished and does not appear to be taking water anywhere. In general, the basement is pretty humid (dehumidifier runs a lot) and seems to be more humid after it rains. My questions are: 1) If this was a drainage problem, wouldn't I be seeing water in the basement walls first? 2) Would I benefit from the installation of a sump pump? 3) Would ripping up the carpet and sealing the floor help resolve the humidity problem?

Considering putting down carpet in my basment, 6 yr old house and very dry basement so there will be no problems.. What is the best type for going rite over besement concrete floor, padding? any and all suggestions would help alot... THANX AGAIN
