The slaked lime is the hardening/binding agent. The nigari, as I understand it, helps to cause the water in the mixture to rise out of the earth as it is being pounded. Although there may be additional benefits to the binding? It seems like there might have been places that didn't use the nigari, perhaps areas where it was much harder to come by in the mountains up away from the sea?

That looks well pukka man,

Do you moisten the soil after mixing but before tamping down or is it all done dry ? Do you have a special tool for the packing part ?

The nigari is liquid so that moistens it a bit, then I add just enough water to allow making a ball by squeezing tightly in hand. Then sprinkling a bit on top seems to be allowing for a better packed finish.

I quickly made some wooden tools for packing using pieces of lumber lying about. Basically just attach a handle to a block of wood and you're good to go.

I realized I never posted a picture of the finished earth floor. It's not perfect, but not too bad for a first attempt, I think.


Here is a picture:

That looks awesome, Brett.
I presume it is also one of those things that just gets even better with use and time as well.

I really enjoy your updates on the kominka and admire the respect you have for traditional building methods.

Looks really good Brett,

It almost has a slightly glossy finish in the picture, is that the same in real life ?

Thanks, it certainly is already changing with use and the short time since finishing. There are areas that are getting smoother as they see traffic/use, and I expect this will continue. I suppose those areas do almost look glossy at times depending on the light.

That's the beauty of the old style handcrafted ways, they often improve with time and actually look better once they've had some use. It really is impressive to see how you have mastered and revived some of these old skills and techniques man and I imagine it is deeply satisfying knowing you have done all the work on your house yourself and have the skills to repair any problems that could occur in the future.

A little work on the small space behind the house.
