I have a bilevel home which has a cinder block foundation and shows some wetness althought not a lot. I would like to finish the basement for ttne main reason being insulation and have had several suggestions.
1. put up a 6 mil vapor barrier, stud with 2x6, insulate with r-19, and drywall.

2. blow in a product called zonolite in the cinder block, stud out one inch from wall and drywall. This contractor assures me this is a much better insulation than method one above.

Any information would be appreciated. I don't want to do all this and then have a mold problem

Zonolite is NOT better than a stud wall with R-19 fiberglass insulation. In fact it is now where near as good.

While Zonolite is a fair insulator the problems are the areas where the web of the block acts as a solid thermal conductor allowing the cold to come through. The Zonolite cannot stop that. The concrete in the block web is a much better conductor than a wood stud making the block wall and Zonolite less energy efficient overall. Then there is the potential of moisture getting into the wall which will further deteriorate the R-value of the masonry wall insulation.

Stick with the wood stud wall and insulation.

PVC panels are water resistant, thermal insulator, termite resistant. Why are you not using PVC panels ( for your basement foundation? PVC will give you not only protection from floor wetness, but this is also budget-friendly and easy to install.
