I am currently in the process of finishing my basement and I want to know whether, in general, anything should be done to an interior cinderblock wall related to moisture protection.
To show what I mean by interior cinderblock wall: In red, I have highlighted an interior cinderblock wall which bisects my basement. The wall has a footer that is in direct contact with the earth.
Should I do something to account for potential moisture seeping in from the footer or exterior walls for this interior wall prior to finishing it? I have a sump pump and no signs of moisture trouble. I definitely want to do as much to control moisture as necessary without going overboard financially.
- I will be using 2" spray foam to insulate and provide a class III vapor retarder on all exterior foundation walls
- I will be using steel framing
- I will be using unfaced cement backer board instead of drywall
- I have a humidifier set to 45%
- I had a sump pump installed last spring. I had very minimal signs of water leakage prior to that time (only once did I have a trickle of water come into the basement when snow was melting and heavy spring rains at the same time). I have had no signs of moisture trouble since the sump pump was installed.
