I too am interested in learning to build domes in Portugal. I was also wondering if any of you have an idea if using these dome's is legal in Portugal. I was thinking of building a number of them, to rent out as affordable holiday accomodation, as well as some for future permaculture volunteers and or a tool shed close to the future farm.
I have been considering this idea ever since I learned of Aircrete. I purchased Geodesic Dome plans from Paul Robinson several years ago and was thinking. Because the Geo dome is very strong, and Aircrete is very light why not stretch chicken wire/cloth on the inside of the panels. Fill them with aircrete. Finish the outside/inside with cloth stucco as normal Domegaia domes.
You would need to leave channels for your screws but that should be easy with well placed straws or just drill out the channels before you set all the screws. This would be a very strong very insulated building. I decide that an Aircrete dome would be cheaper because I don't need all the limber and screws but still a very cool construction idea.
If anyone uses my idea thats great just document and post. WE all are learning.
This is just not stopping at all, there are 88, 656 confirmed cases already outside of China. I hope this will not get worse than this. So in times like this, we need to have emergency tools at home because we will never know when we can go out safely and if our need will be available. High lumen flashlights are of great use, I recommend you try Streamlight Super Siege https://totalguide.org/best-tactical-flashlight/streamlight/super-siege-review/. this would be a perfect light for the house in case of power shortages.
@Kintore Hi, imagine you are in a hemisphere and walk towards the perimeter. How close can you get before bumping your head. This is one of the biggest benefits of the Domegaia solution - you gain all that space under the curve. The other benefit is aesthetic - it looks beaut!
@Samson-Jones If you have not already tried this. I would say aircrete used directly as flooring will flake off a dangerous to inhale dust. So no, I would certainly coat it with a "milk" layer that includes laytex.
I thank you both for the information. As mentioned I don't think there will be much of a load on the steps and the footer under them. I too am in Hawaii--on the Big Island in North Kohala. I want to use aircrete but only if it is 'doable'. I was reading in the some of the posts here, that the use of a 'fabric' adds the much-needed strength to the building as a whole. I'm wondering if it will add some compression strength to the steps and footing if I were to wrap them, once completed in the fabric that is set in 'airmortar'. I am very new to this and want to do more with aircrete in the future, that is why I would like to figure out a way to do this footing and set of steps using it, instead of the 'quickcrete' that I have used in the past for projects. I like the idea of a 1/2" of mortar over everything and even using tile over the aircrete seems like it would certainly disperse the compression load. Any and all comment/suggestions are more than welcome. Mahalo for getting back to me. Aloha...
