I've started a project! I'm still looking for suitable and affordable land for my cob home so in the meantime I'm getting familiar with some natural building materials. I live in an old house, built around 1890 with multiple additions. My west wall isn't well insulated and my kitchen pipes freeze every winter (I'm in central IL,USA). My plan is to tear out the entire kitchen wall, pack the space between studs with slip-straw, and finish with an earthen plaster. I'm starting with a small section as a learning lab. Yesterday was demo which I finished today, and started my first foray into slip-straw.
Lessons on day 1:
I definitely need to round the handle of my pounder. Even though I sanded the edges and corners, my hands are still feeling it.
Slip-straw has a bounciness I didn't expect. I hope I compacted it enough. We'll see tomorrow.
I'm starting to understand slow, yet immensely enjoyable building. Heart and soul are ingredients you don't see on any materials list.
I have read differing opinions on how quickly you can remove the forms. Some say let it dry at least overnight, some say you can remove it right away and keep building the next level. I wonder when you keep working right away if the base put. Anyone have experience in that?
