Naw, Kevin. This ain’t settling. This is the concrete reverting back to its original state, i.e. lime and whatever. It’s a surface thing. I’ll send an iPhone shot to your email, I hope. As for our house breaking up in The Big One, I doubt it, since it’s made mostly of cardboard. A few years ago during the Northridge quake, my wife and I stood in the hallway and watched the walls sway, but never crack. In fact, we never even had surface cracks, like in the ceiling. So much for shoddy construction. As for our Buffalo house, its basement never leaked, 'cause if it did, Dziadzia" and Babcia woulda drowned, since they lived down there. It was private, very cozy and warm in the winter because the oil-burning furnace was there. Cool in the summer, too. Gee, I miss my grandparents. BTW, did I tell you that a guy from our old 'hood (Fillmore and Best) lives four doors away? Talk about small world.
Vic, I’m having second thoughts about that foam, which is brown and very granular. All ya gotta do is touch it and it begins to disintegrate into fine powder, which makes me wonder how much of the stuff I inhaled when I was prying it off the walls. I have stacks of the stuff and it’s tempting to use it, but you would definitely have to seal it to keep it intact. HD sells similar looking stuff (it’s about 2-3/4 inces thick), but if I was gonna use anything it would be the blue or pink foam, which sits right next to it at HD.
Of course, first I gotta finish my garage/man cave–sanding the tape joints, painting, and installing the last melamine cabinets. Then I can get back to trains, while taking me wife to chemo camp every week (a story for another time and place).
