Please see the references in my previous comment. I don’t agree, especially if the top, exterior portion of the foundation is exposed. Please see the references in my previous comment.

You REALLY need to create a vapor barrier to prevent moisture that's in the foundation wall from entering the finished wall cavity. You should read these articles:http://www.homeconstructionimprovement.com/how-to-insulate-basement-walls/ http://www.homeconstructionimprovement.com/vapor-barriers-for-basement-insulation/Cutting a whole in the drywall won't allow you to get a uniform application of any spray product.

Cutting a whole in the drywall won’t allow you to get a uniform application of any spray product.

So what, you might ask? Well, Spray foam insulation traps water and moisture in the block wall or between the wall and the foam. This moisture has nowhere to go but UP, especially since a building's air movement is upwards (Stack Effect). Up above the foundation is a sill plate, floor joist, bandboard, and subfloor. These are all wood components that are susceptible to wood rot and mold growth when the moisture content in the wood rises. i also found this online which they say to never spray foam your underground foundation, do you agree with their statement below?

1 – cut out some drywall at each framed section
2 – remove the fiberglass insulation
3 – have nu wool cellulose spray foam sprayed inside

will this work? will it stop the moisture from getting to the drywall and prevent mold? i am trying to figure out the best way to combat the old foundation wall made from cinder blocks without excavation all around the house or demolishing my finished basement.

(the current mold is more likely from a backflow from the toilet and not the foundation wall, the fiberglass and wood studs do not show any mold, YET!)

However, it's very important that the installers follow industry standards. There are some installers using as much as 5 gallons of water per 30 lbs of insulation which is much higher than the recommended 1.5 to 2.0 gallons per 30 lbs. Having said that it's possible that either your situation was too wet (didn't allow proper drying time) before drywall and/or the insulation had too much water to begin with.Not really sure what moisture meter to use, I would remove a sheet of drywall and inspect the insulation, find out how wet it really is.

My brother had wet cellulose installed in at a home he is building. After it was up, drywall went up. When the drywall installer was done (mud and tape has not yet been installed) he noticed some wet spots on the drywall. He is concerned the cellulose was not given time to adequately dry, and moisture will affect the drywall and any mud and tape he will install, and possibly future paint.My question is, do you know of a moisture meter that could be stuck through the drywall into the cellulose to see the moisture content? And if it is still wet, can the moisture pass through the drywall without hurting the drywall?Thanks for any information. Question about moisture.

My question is, do you know of a moisture meter that could be stuck through the drywall into the cellulose to see the moisture content? And if it is still wet, can the moisture pass through the drywall without hurting the drywall?

Thanks for any information.
