Day 335: more rain

Day 335:

Another rainy miserable day outside but I was determined to get the ceiling/roof up in the chamber that I’m planning to cover with dirt.

It leaked like a sieve.

My current technique is to cut the stones such that they lock together pretty solidly, but that doesn’t do much to keep water out. I’m pretty sure that once I have dirt on top it won’t leak as badly, but I really could use some tar or something to keep the leaks out a bit better.

No idea how to make that though so it’s not a today project.
