[papercreters] Papercrete in the Tropics, review

Hello,
I am new to Papercrete and new to this list. My name
is Robin. I live in the Peruvian Amazon in tropical
rainforest conditions. I have browsed a few messages
about papercrete in the tropics.

Needless to say, reliable dehumidifying systems as
mentioned in these messages are pretty much out of the
question in the rural areas where I live and work. I
have a few thoughts, and would gratefully receive any
further insights or places to turn, especially from
anyone with experience using papercrete in the
tropics-subtropics.

--Traditional houses here are built on stilts, usually
wood, but acceptably with concrete (cement-sand-gravel
mixes usually) as a major way to reduce moisture
absorption from the ground into the (usually wooden)
structure of the house. This seems like a useful way
to reduce absorbed water into a papercrete house, as
much of our water issues come from the ground rather
than from condensation from the air.

--Does anyone know how much of a factor condensation
on papercrete surfaces really is? Cement or wooden
houses dont seem to suffer from condensation here, at
least not noticeably.

--What are some cheap, reliable products for sealing
or waterproofing papercrete?

--Any experiences with timbercrete in the tropics
(sawdust plus cement)? I have made a few blocks of
sawdust-sand-cement mix with pretty decent results,
though a longer drying time.

Any general places to turn are very helpful. Thanks a
lot,
Robin
