Cob: Basementphil phawn1 at excite.comMon Feb 10 10:03:05 CST 2003
I'm no expert (though I've acted like one often enough) but if you only have a basement area in a central part of the house and not approach the outer walls at all it shouldn't be a problem. This is what I plan on doing. My cellar will only be under my kitchen area which should be a good 15 to 20 feet from any outside wall. Hopefully at this distance the weight of the cob or the bermed north wall won't have any effect on a basement area.

It's a difficult site. I told him what I was looking at, what kind of a building, what I had to do to even start on the building. Asked about both retaining walls and the footings/foundation. He said, "no problem, all I have to know is how heavy your building will be, what your soil is like, how steep the slope is, and I can calculate hydrostatic pressure and draw these up for you.." Or something like that. Not the only reason I abandoned that plan. May go back and ask him for advice about the current plan, when I get closer to building. If you try something more than burying the back wall a couple of feet up, DO get an expert opinion. You may not be able to guesstimate the footings, which spread the load out over the ground (WELL below ground). The guesstimate is twice your wall width--but you're proposing a VERY heavy but small building. You need strong and waterproof for your basement walls, which probably lets out cob for all but an inside wall facing. And these walls need to support your cob above ground. The cost of the basement may well be more than building another (cob or something else) structure to house what you wanted to put in the basement. But the walls are no more likely to cave in than any other equally heavy building on a similar footing/foundation. .................. Chandra asks: I am new to the list. I have scanned the past year or so archives and I have not seen this topic addressed. Is it possible to have a basement or even a cellar in a cob home? I would like one. My husband thinks the weight of the walls would cause it to cave in. _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
