Rob spent a lot of time clearing the crawl space of the discarded systems and pipes, and then, with the help of some friends, we had the crawl space dug out to an even depth of 2 feet throughout. The most exciting part is that we had a new cellar floor and the entire crawl space poured. Here's some pictures of the process, our cellar, and crawl space, sans the dirt floor.
Gearing up to pour the floor:
