"Good Home Builders" that didn't waterproof the exterior side of the foundation walls? Seems like an oxymoron to me. But then I've seen very few "good" home builders.............. most of them are what I call Checkbooks. They write checks (as cheaply as possible) to other people to build a house that they will then sell at a profit to someone else. Most don't know the difference between a 16 penny nail and a deck screw. I like the one that told a homeowner once when asked if the drive way would crack....... "I have two guarantees about concrete. It will crack and it won't burn." Guess he never heard of compaction or an expansion joint........ much less wire mesh.........
Hello I am a contract carpenter retired. To finish the basement walls you should cover the walls with light grade tar paper first tis will stop water from making contact with any wood products. I all ways frame the wals will 2x3 and leave a space between the exterior wall and the frame about 1" So you can slide the foam in to and tape the joints with tuck tape . Use a plastic barrier under the frame to stop water from making contact. The frame work should be framed at 24" centers that will give you a space for insulation R12-15 Do not nail to the walls. Fit the frame work tite between the floor and ceiling.This will give you a worm and dry basement. I hope this helped my name is don
you need to keep in mind that the insulation should not be too close to the concrete walls. they become worthless if the moisture from the concrete reaches the insulation. it might also spoil the wood.
