foundations and slabs

Now that we have pretty much gotten through the whole site clean-up process, we can finally start looking to the rest of the build process.  We spent way more than what we were expecting to clean the site up, but hopefully we will be able to stay closer to budget from this point forward.  Anyways-  as the foundation is being poured this week, my thoughts are moving towards insulation and waterproofing.

The house is a hybrid.  It has both a crawlspace as well as a slab.  That means insulating the house needs to be slightly different also.  I plan on using 2 inch thick extruded polystyrene boards.  Around the interior perimeter of the house I am going to line the foundation walls with it using liquid nails to hold it in place. Under the slab I am going to lay a 6mil polyethylene vapor barrier over the stone lay the insulation on top, and then the concrete right on top of that.   In the picture below, I plan on using the option to the far right.
