Paula,
Cob pool reminds me of something I saw posted when
I first joined this list. One of the members had posted info on a "dew
pond". (Stay with me while I explain my idea.) I did some research
on these dew ponds which have been built in Great Britain and a little in
Canada. There is a widely believed myth that they are formed from
condensation of water(dew)--it is a myth based on an erroneous old text which
describes a pond made of layers of clay and straw in which water almost
impossibly appears from dew. The ponds do exist but from my research I
have found that the water they contain comes from rain not dew. (No
offense to the original poster--I had to find at lest a half dozen
cross-references to root out the truth.) Anyway, what they are are in fact
artificial ponds created efficiently with local materials before the
existence(or to avoid the expense) of cement ponds. Their purpose was to
provide a water source on high chalk cliffs where the land drained water so fast
no streams or lakes could exist naturally. The ponds had to be carefully
constructed with first a layer of dry straw, then a lipped basin of clay, then a
layer of rocks to prevent cattle walking through the water from puncturing the
clay and ruining its water barrier. These ponds were vital to allowing
ancient people to live where there was no ground source for water. And
only really worked in a place that rained enough to keep the pond full.
Here's where this relates to you. If you want to build a sunken pool out
of cob, what you really are doing is creating a artificial pond. I saw
recently articles in both Mother Earth News and Natural House Magazines(in the
US) that described how to make your own "natural" swimming pool. What you
want to do isn't exactly what has been done, but is similar to these ideas I've
mentioned. What I would suggest to you is to think of your swimming pool
like a little pond not a bathtub. Let me point out that since you won't be
draining your pool and it (probably) won't contain chlorine and have a
filter(the mud would clog it) then you must include aqueous plants that will
naturally clean your water or you will end up with a toxic water mess. So
check out these magazines if you can for info on how to build and plant a
natural pool. The thing is that most natural pools use a plastic pool
liner to prevent the water from seeping into the surrounding ground. What
you could do if you want is to use the straw and clay construction of the dew
pond. It won't be cob exactly, but well you'll already have the
ingredients if you are building a cob house.
Anyway, just a thought...hope it
helps...

Bathtub??
Hello everyone!
My hubby I will be building a mud brick house within a year. We just
got
the land, well almost, still have to sign the contract. We live in
Sydney,
Australia the land is in Cowra.
My question is: Is it possible to make a swimming pool bathtub out of
cob
or clay?
I know we would have to seal them very well. But, with what? I
have tried
to look on the net for some info, but have found
nothing. What do you guys think?
Thanks!
Paula
