You want to remove all moisture and tank the basement. The tanking requirements depend on how good or bad the water table is in your area, this will be the water pushing from the bottom up or through the wall. Alternatively , if there is not a correct damp course above the water or sweet marks will make there way down the wall. Try a dehumidifier to start and see if you can remove all moisture. (these are good will answer, anything stated is to be checked by myself or by a qualified and compitatnt engineer)
