No footing under crawl space wall?
Good day everyone,
We just bought a house in Northwest OH (built 1990). I have been reading a lot about crawl space encapsulation on various internet sites recently. It seems like something that would be beneficial and that I could do myself. So I was looking around down in the crawl space yesterday just to get some ideas on how I would proceed, and I noticed that there doesn't seem to be a footing under my roughly 3' high crawl space walls. I can reach under it quite easily with my hand (there was some loose fiberglass insulation that had fallen down in there). Also, it looks like there is a 2x6 or 2x8 under the wall. I am new to crawl spaces, so I really don't know what to think of this. Shouldn't something be holding the crawl space wall up? Why wood anyone put a wood board under the concrete wall? Should I fill this space in with gravel? Is it actually a poured concrete wall or some cheaper alternative? Thank you for your help.
