I had to work today, so all the fun stuff was done by the time I got home. From what I can see, the seams were all coated with a tar-like substance, and the walls are covered with something that looks like insulation. As you can tell, I'm all about the technical details! I'm off tomorrow, so I'll find out exactly what was done.
This will be the front porch.
Obviously the drainage tile is working.
On this one you can see the tar.
