See what I mean about being a dinosaur? I figure most of the problematic
domes I repair, are the result of just what you describe....shoddy or
incomplete construction methods.
I also totally agree with the whole idea of the flowing shapes and arches
that are achievable with concrete domes. Also being unaware of any
crystalline substance to fill cracks is a factor has flung a little egg on
the ole noodle , but I do admit my observations are just my opinions.
 So maybe I DO limit myself but like I tell a lot of my clients. If I quit
learning...I must be dead. Thanks for the insight. JJ

Hello John,
You are not stepping on toes but you are limiting yourself by keeping your
path limited
to building with the materials you have always used.
Yes, concrete cracks but so do the 2x4's used to build domes. Do you expect
your raw materials to
keep out the elements? NO.
Just like with studs and crud, concrete shells need a roof or a layer of
sealant to keep out the
weather.
Right now I am restoring an underground concrete home. It is a group of
connected domes. It leaked 
terribly from the beginning of its life 20+ years ago. Was it the concrete's
fault? NO, The owner 
builder covered the structure with a couple layers of plastic and expected
it to be a good roof. we 
have removed the dirt and applied a fresh layer of shotcrete with a chemical
to grow crystals in any 
cracks. I am not planning on that being my 'roof', it is just an extra layer
of insurance. with just 
this new layer we have a watertight structure. For the roof, we are adding a
polyurethane roof 
coating.
The reason I tired of studs and crud domes was the limiting factors of
shapes. With concrete I can 
have domes, arches and free flowing shapes that feel much more pleasant than
trying to fit a 
shelter/home in a bunch of triangles.

Best regards,
Nolan Scheid
