Hi Kelly. Last year I invented a new way to build geodesic domes. Here is the lastest video that I posted to Youtube. This was my first wooden dome (There is a smaller PVC dome inside it). The wooden dome is a 2V / 12.944 Diameter. The wood was cheap 1 x 2 furring stips ($1.10 for an eight foot piece of lumber). I can use metal struts for a more sturdy structure.
I'd like to cover or wrap one of these domes and then plaster over it. I was also thinking of wrapping the dome using a silt sock (filled or unfilled) instead of covering it with a 2D sheet of canvas and/or hardware cloth.
There is an example of a filled sock,which is kind of like an earth bag:
The sock would most likely be filled with a lightweight material like straw so I'm thinking this would be similar to covering an earthbag home and/or a straw bale house with plaster.
What do you think of such a building method. I'm thinking that by using a geodesic dome one could build a bigger structure.
Do you see any potential problems that I should be aware of?
I plan on using a mortar sprayer and surface bonding cement. Does that sound about right, or would you suggest hand troweling a different kind of plaster?
