Darin and Greg worked on the crawl space today in spite of the extreme cold. Insulation was applied to the inside walls. The water barrier cannot be applied to the outer wall until the cement blocks are dry - maybe in a couple of days, perhaps Saturday. The extension near the front of the photos is for the fireplace. If the water barrier is applied on Saturday, then the guys who dug the hole for the crawl space will come on Monday to back fill along the outer walls.
