Having removed internal walls and plaster, we’ve found lots of holes and gaps in the walls which will need to be filled before the insulation goes on.
The building is constructed of wood frames in-filled with cob, a mixture of local clay, sand and straw. We’ve never worked with cob before so we turned to our friends Chris and Claire for advice. Chris showed us the local clay pit, and Claire gave some advice on getting the mix right.
Working barefoot was definitely easier, and actually quite satisfying, getting the mud to ooze up through my toes! The mix has gone on well, and all the holes are filled, but we don’t think we had enough sand in as it’s shrunk quite a bit. It’s not fallen out, so it will still work ok, but we’ll adapt our recipe next time.
