Basement Insulation

Basement Insulation
We are currently finishing out our basement. There are moisture problems in the basement. We have a sump pump and are in the process of having gutters installed. Also, while prepping the basement for finishing we dry-locked the walls where moisture appears to seep. Hopefully the moisture issues will be resolved.
The framing sits about 2-3" from the basement walls. What type of insulation, or combination of insulation should we use? There is one wall that has been damp. The other walls appear fine. Should we use a rigid or closed-cell insulation on the damp wall and batt elsewhere? How should the insulation be installed?
Should a specific vapor barrier be used, or will the 2-3" gap suffice?
Also, should we remove the insulation on the ceiling now that the basement will be finished and heated?

The best advice I can give yo here is be patient. Applying the drylock and installing the gutters should improve things for you in the basement however they may not be the only source for the moisture in the basement. You should wait and see if the things yu have done actually prohibits the moisture in the basement before finishing it off.
The gap between the framing and the basement wall is sufficient. In your area fiberglass with a vapor barrier is installed with the vapor barrier facing towards the inside of the basement. Again I recommend you wait and see if the steps you took to prohibit moisture in your basement actually works before you finish off the basement.

I am no pro, but I agree with resercon. Here I scraped my walls and got as much eflourescence off the walls, put lots drylock on, worked on my negative landscaping in the yards,and put like a black roofing cement in between my outside wall and the driveway, water liked to go down that wall. That was a yr ago, and I still have some seapage through the walls.I would say make sure you do everything outside you can to drive the water away from the house, and give the walls ample time to dry to put on the drylock.
