[Cob] Radiant floor and Rocks in wallsDulane silkworm at spiderhollow.com

1) In cob, I don't have any experience with radiant flooring, and my little hut was too small for me to consider the process, as it heats very quickly anyway. But I poured 4 inches of cob on top of pea gravel, separated by large pieces of 2" foam insulation this summer.in advance of a finer cob mix for my waxed and oiled top layer. The difference in comfort is amazing. There is no draft from the floor up anymore. I think that the temp is even throughout now. With a carpet on top of the coarse cob, my feet don't get cold anymore. In the summer, my dog used to love that cool pea gravel, as it wicked the temp and dampness from down below. If you used radiant flooring however, you might be able to pump cold water through in the summer, and cool the floor that way. Like using a cold waterbed in a hot house. Couldn't you use solar panels to pump water? 2) About rocks in walls. I sure buried a lot of fist size rocks and urbanite into my walls while building. In the center of the wall, I don't think there would be any issues. For rocks that are external, for decoration or otherwise, if they are protected from moisture retention, I think they would be fine for many years. Remember that many minarets and other tall earthen structures had large rocks (or wood) extending from the walls to use as steps. As long as the rock is deeply embedded, with the heavier part buried inside a wide wall, the rock should be fine. Hint: Don't put any weight on these steps until the wall is COMPLETELY dry. Dulane
