Hi Guys - Thanks for the input. I must admit, I think this is the most interest I have ever generated in a thread on AVS - very exciting!
Having said that, you're scaring me Drew! The horror stories of basement water here are what prompted me to get into all of this Drylok, moisture, foam etc. stuff.
My house was built in 2001 (I am the second owner - purchased in April of this year) and, although I don't want to jinx anything, I have had no moisture since taking possession (other than when I had the A/C replaced and the technician forgot to hook up the line to the condensate pump and it ran for 2 days before I noticed - NOT funny - soaked the half of my basement that is already finished, but that's another story).
So anyway, I had a few tiny hairline cracks in the forms that I patched with Drylok FastPlug, then put Drylok over the whole thing, just for good measure. I haven't seen anything that would indicate that I actually needed to do this, but again, I'm admittedly anal
. I cut and dry fit most of the insulation last night and then actually applied about 1/3 of it.
My method was to use four evenly spaced horizontal lines of PL-300 across each piece of foam. Then when starting the next piece, I repeated with the glue and added a small bead of Great Stuff to the tongue and groove joint to try to get a good airtight seal between boards. I then taped the seams with Tyvek tape for good measure. This solution worked very well, although it was definitely overkill on the glue (but I wanted to be sure I didn't end up with big air gaps).
To anyone who may come across this thread in the future - I am clearly a spaz and this method is overkill given my particular situation, but to me, a few extra hours and dollars now has the potential to prevent disaster later, so is 110% worth it IMHO.
Thanks again to everyone for your input - here's a pic of my progress so far...
That gray fireproof cabinet is just there to be sure the boards don't pull away from the wall at all. It was a house-warming present from the previous owners (more like it weighs about a gozillion lbs. and you need a crane to get it up the stairs, so they just left it).
