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 (https://www.delpro1238.com/) for your basement foundation? PVC will give you not only protection from floor wetness, but this is also budget-friendly and easy to install.
