I am sure they would have done better if completely coated in ice dam membrane or sprayed with something like truck bed liner as the roof. But then you have moisture build up because it doesn't breathe. Can't win, the design just doesn't account for moisture in the walls.

You got me wanting to do something, rather than talk about doing something - cf. my signature line thing - Last summer, I cleaned up the "garden" at the University (the quotes are because, like it or not, suburbanite undergrad kids are all talk hence the need for me to go clean someone's project that they half-completed, then left to tweet about how green they are...) I ended up with some free PVC, among other things...
So! Twenty minutes, a chunk of rope and some electrical tape - and I built a wonky Octagonal-Catenary-Reciprocal-Dome-Tensegrity!! (O.C.R.D.T... Ocdirt? Ocridt... ??)
It has no foundation, thusly I used rope. The rope would not be there of there were some nice buttresses due to some earthbag or tire or concrete knee-wall.
One picture is overall, one is closeup to show the weave, one is from inside to show the star-ish pattern, and one is where I squished it to show that you can mess with the arcs to make.
Put some ties or bolts at the intercises, and again cover it with the "hypar" DIY concrete cloth... My neighbor said it looks like a tent and I thought that was great - it's like a concrete tent!
I realize it's unlikely that anyone other than me would be very enthusiastic about such a screwy looking thing, and yes - it's probably been done before. I don't care! It's mine! MINE!! HAHAHAHAHAAAAA!
But, anyone can use it if they want :)
