A photo from today; the drain mat is in place along the back walls. This is neat stuff, it conducts water inside, and protects the back wall waterproofing from rocks and etc, and still works even when compressed by the back fill dirt. The idea is that any water that does get to the back wall will be channeled down to the french drain at the bottom of the wall.
The dirt contractor also brought in a much larger front-end loader today, so the back fill should go much faster than with just the track steer. I'll get a photo of it tomorrow or the next day.
