All the drain lines have been installed and are ready for pressure-testing today.
After the test, the trenches the lines are in will be backfilled with sand and he can start placing baserock (capillary break), vapor barrier, and the thin sand layer in preparation for concrete placement.
We are using Stego Wrap (http://www.stegoindustries.com/) instead of visqueen due to it's superior strength and vapor blocking capabilities. This is a first for our builder, and he thinks he might start using it on all of his future projects. I need to double check and make sure he's going to be placing it in the garage as well to help prevent efflorescence.
He may be placing concrete on Monday for the house and garage slabs.
Our family is going out of town for Thanksgiving week, so I will miss part of the fun.
