Hey everyone, Here's some video compilation of the earthen floors I've been working on this Spring/Summer. Lots of bits of knowledge in here for anyone interested in doing earthen floors. They're really wonderful, but they are definitely a challenge! See what trial and error we've had to go through so far with these floors and this soil.
I wanted to post some of the photos from the Cob Hobbit House build. I was thinking of doing a live Q&A call for you to ask questions about this build, but let's start here...post any questions you have regarding this one. I have more case studies in the works. I'm currently compiling one for the Florida Cob Cottage and the Cob Quonset Hut. Spring projects are ramping up though, so I'm a bit behind on all the digital online work. Thanks for your patience!
@Keith Corona Yes, this foundation was dry stacked, and I only pointed the exterior joints with mortar. Now, I would not do it this way though. I would mortar all of the stone together for a stone foundation if you have mortar available. Probably best to use a lime mortar since you don't want mortar that's harder than the stone itself.
Wattle & Daub is an earth building technique that's not often talked about these days. It's basically a thin cob wall built between post & beam and woven lattice. I don't normally recommend wattle & daub for exterior walls unless you live in a tropical climate. The walls are too thin for substantial insulation or thermal mass. But they're quick to build and work great for natural, non-toxic interior walls in any home or building.
Hey all! I'm getting ready to start breaking ground for a sauna and was thinking about experimenting with a hybrid. I'd like to make the stem wall from stone and make the north wall slip straw and the rest cob. My question is: when setting up the slip straw forms, how do they attach to the stem wall or do they attach? Thanks for any info!
Hey Becca, For the slip-straw forms, the temporary plywood forms just attach to the wall framing. The wall framing is attached at the bottom to the sill plate (which sits on the foundation). I know this can sound confusing. It think the slip-straw section covers this with enough visuals, but let me know if you need more clarification.
I was able to join the workshop back in May. It was so great and well worth it! Here's a little video I made from my experience. So if you're on the fence about going in the fall, just do it!!!! No regrets! https://youtu.be/pPa8MZoD6ec?si=kI1vazn9qQslNHXP
