[Cob] Silverfish, Tornadoes, and Humidity

[林雅茵]

I live in Taiwan, a seismic zone, and I wonder if it would be wise to apply
pure cob wall system with stacked foundation, yet I do very much prefer one
whithout much compromise.

Well the obvious answer is don't use a dry stacked foundation, a simple
lime based mortar while not particularly strong will give it additional
stablility as well as keeping out insects, reptiles, etc.

As far as round rock, it depends on what you mean, if they are really
round or close to it, I probably wouldn't use them, but if you just mean
irregularly shaped rocks that are not flat on two opposing sides, there is
generally nothing wrong with using these, though it will require more
mortar, and if you are in a seismic zone, depending on your design, it may
be desireable to use cement and/or rebar with the rock to give it
sufficient strength.
