Saw your hexayurt today, nice. I've worked on similar projects years ago. A few
things that might help
1. Bifurcated polypropylene carpet backing. Very inexpensive lay on top of
panel dust with dry mortar mix, add another layer of same fabric mist with
water and you have an insulated panel has tremendous strength, especially if
done on both sides. Still relatively light.
Also have an method for vertical application.
2 Tirolessa cheap cement sprayer
3. Boat shrink wrap lasts at least 1 year. Can be obtained in very large sizes.
Works great on PVC pipe frames. Fast strong relatively cheap 10 cent ft sq.
Also works on panels very weather resistant. Tape is excellent. They also have
inexpensive zipper doors and vent systems for moisture because it is airtight.
4 basalt fiber fireproof almost as strong as carbon fiber priced closer to
fiberglass Truly amazing product comes in many forms a bit difficult to obtain.
5. Continuous plastic hinges good for over 1 million cycles 100lbs per foot.
Weathertite uv resistant.
6 PVC pipe hinges cat small diameter PVC pipe 3-6 inch pieces alternately
attach to panels ends slide rod sized to inside diameter of pipe.
7. Lightweight concrete
