The foundation is now mostly complete with the addition of a third course on the west side of the building. The past few days have been spent trying to piece together that topmost course with the remaining urbanite, and stuffing additional nooks with a clay/sand mortar. The construction of the foundation has gotten funkier over time since we used all the nice flat pieces at the start, and all that was left for the third course was the irregular stuff.
The mortar mix is kinda tricky to work with because of its high sand content (about 3:1); it’s very gritty and difficult to jam into tight spaces. I’m glad now that there are only a handful of cracks remaining. But it sure does feel great not using any nasty new cement mix!
On Monday, I hope to get a delivery of sand to begin cobbing the walls. Look out!
