Jason here in Mexico. I had an idea come to me and wanted to pass it
by you all. Okay, let me try and explain it. This is being done all
over but I am trying to use a little Mexican ingenuity, to reduce
cost. I build a 51ft. cement column in a perfect circle about 3
meters off the ground with pillars holding it up. I go to my tarp
friend who builds blow up playsets that the kids slide and jump on.
He builds me a blow up dome (airform) 50ft. x 15ft. with the cheapest
tarp pieces available that will sit on half of the circular column 3
meters off the ground. The blow up tunnel will be on the
bottom/center of the tarp dome and go to the ground 3 meters. The
bottom of the airform will be supported by 2x4's and whatever we can
find to hold it up. Put a rebar web around the airform almost like
ferrocement that connects to the column. I will buy a sprayer and we
spray that baby with pumicecrete about 3-4 inches thick. There you
have it. Then we cut the airform up to make different shapes and
build thin walled dormitories around the conference dome. Paint it
with adobe colored textures and make them look nice.

???? Beside the pump and blower, I am wondering if the material would
be super expensive? Does anybody know if there is a cheap pump that
could handle this?
