Quoted from toyotaboy:
Serious question (and I know codes vary by area). Based on what I've read up on, If I wanted to throw up some walls in my basement I need:
* pressure treated lumber on the bottom plate for the wall frame (optional if I want to use nails or tapcons to secure). This is so that if I should get a flood, the base is waterproof
* Ideally I should have an insulation barrier between studs (either fiberglass or pink foam)
* I need a moisture barrier (IE polyurethane sheet at least 6 mil) on the outside before the drywall so in case moisture somehow gets through, it won't rot from the inside
Assuming I don't also need a moisture barrier behind the wall (I do plan on coating every concrete wall with drylok) ?
I'd like to get some real flooring down at least partially, and I don't want to do that until I have some real walls up. I also plan on using dricore tiles before I put down anything on the concrete floor.
This is almost exactly what I did. If you do have a moisture problem, Do not use fiber batts; it will never dry if you are putting the studs right up against the wall. Use foam board (make sure you buy a hot knife if you are installing yourself!), or do spray foam. Spray foam is pricier but you get a better seal and R-value is a little better. Batts are the best; but you need more space.
I built our basement 2 inches off the concrete so air can get in anywhere it needs to, in the event we have major leaks, and the fiber batts never touch any moisture.
So far so good, and no real need for the moisture barrier except on the floor. IME this is a superior design to jamming everything in air tight and trying to squeeze out every inch of space. Air tight means water like.
I also did dricore, and if you have the ceiling height, it is awesome (although a pricey subfloor..) be careful not to pierce the rubber layer, as any water can wick up into the OSB on top.
