[Cob] Can I lay tile over a cob subfloor?

[Jill]

I would do any of that I would just oil the floor well. Do you have a 
stone foundation with no plastic as the water will then just filter 
through and disappear. A friends house was filled with water from a 
river flooding nearby. She couldn't deal with it right away and when she 
got to it about three days later, there was no trace of the water it had 
just filtered through the floor and into the earth below. Waterboard 
wont allow the subfloor to dry and then you will be creating problems. 
Barriers are problems, free flow is natures way of dealing.

I am OK with bedding them in a layer of the finish cob with a spacing between them to allow for cob drying (with cob well oiled and waxed), but my husband is not sure this will keep it dry enough. He is keen on a layer of thin waterboard over the cob subfloor, with the tiles laid on that, to prevent any water getting in. I don’t think we need to go this far, but would love some insight.
