I'm finishing my basement and i found what i hope is just mostiure/condinsation on the foundation wall above the frost line ( about 2 feet down from top of foundation and runs the entire length of the wall ) There is enouph there to make your hand wet when you touch it. I would think this is not normal? the house is 3 years old, also there is a about a 1" gap between the foundation and the studs i'm not sure if this is normal?
I should also mention that i have not seen any water on the floor
Here is how you can determine if its from the outside (leakage, seepage) or condensation from the inside.
Dry off an area, maybe 2'x2'. Tape a clear plastic sheet over the area with duct tape. Leave it alone for a few days. When you come back to check if moisture is on the surface its condensation, if under the plastic is seepage from outside.
The fix will be completely different depending on your results. Same test technique works on floor.
