sorry i lost ur mail.... now i got it 🙂
JOHN, as i told u that i will not build a dome anymore. it was a nice idea.
i made different types of bricks, i still have some samples. and the tool for the foam. it works fine. u have to experiment urself, then u will see, its not as easy as u may think. to build the foam mashine was the most difficult, to make the bricks was just easy. u can get the mashine for a reasonable donation even the foam liquit if u want to make ur own experience.
There is a builder in Florida builds storm domes over 20 years.. he may know still trying to find him over Internet.. he a business person Florida been into dome storm shelters long long time .. I was just at that site alibaba and saw portal domes easy to build one day ship you a dome less 8,000!!! Or 5500.00 bucks can’t buopd with aircrete etc I look at all that is out there just for knowledge education I go everywhere to find out stuffs.. only state truly had no building codes is Texas .. Wyoming you need sewer but rest as long it’s outsyde city etc some putting tires on domes because they laws are so bad turn domes into mobile homes .. the system is for tree based homes not ego friendly .. all I can say loops holes.. their maybe me laws that use write as a emergency shelter so it bends the rules in your favors Montana is sorta ok but still reservations it’s worse my family lives pow camps that can’t some pow camps plant a orange tree afraid we’d over power the federal government it’s that bad America.
@HandyDan Clearly. Thus, the question is, given that the foam collapses under pressure, therefore requiring shallow pours and thereby creating layers: how does one create a sealed form that is fit for purpose? It is imagined that it would be best conceived as either a multi layer form that is added to layer by layer, or a form that can be raised and adapted to the next level.
Having no form work experience, I do not have the answer.
Can you pleas describe or provide a link to this "Dresses foam agent"? I can't find it.
There are also other almost identical foaming agents available at local farm stores.
They are used for "row marking" where the tractor squirts droplets of foam so they can mark where they went.
@Kwagga sorry I don’t understand your question? Vids or pix of what. My project? I’m tearing my hair out trying to get a quote for the footings from local builders. They agreed to provide a quote in January and still haven’t come through.
@Traveller 04: the clay soils have been classified as “highly reactive “ - which can experience “extreme ground movement” of more than 75mm when wet. I don’t know what this would be like for a rocket mass heater but it’s a bugger for foundations. My footings will have six rebars top and bottom to create one bloody solid raft to support the domes.
I'm developing a DIY round 3.5 foot window kit for domes. My question is, are there any folks here that would be interested in receiving all the parts and instructions to build on site a round window jam and frame? The only thing necessary by the customer would be to assemble the form, buy the glass cut to fit and mix/pour the cement for the jam. The Windows can come in all sorts of sizes and functionality. Most to all of the woodworking would be done for you with minimal skill necessary for assembly.
@fire Earthbag construction is so labor intensive but not as labor intensive as packing tires. I personally am going with the Monolithic Dome airforms. You could make your own airforms I have not done so myself, but i visited a home in CO where the home owners made the airforms. On there website they sell a book on how to make airforms.
Here is a video I made of the home i visited and I have a link in the description to the website with the book.
@Martin10 if my calculations are accurate then you should need about 2800 blocks. This is assuming a consistent block size as your estimate for a 16 foot diameter dome. I simply took the square footage of a sphere of that diameter and divided that to get a per block ratio (.867 blocks per sq ft of sphere surface area calculated at some diameter) and scaled it. Assuming that you have The same fraction of the dome above the ground as in a 16 foot diameter dome that should be a rather accurate prediction. I could model it on CAD very quickly if you want to get a more accurate number. The fact that it is nearly 4 times the quantity also gives me confidence because the surface area quadruples as the diameter doubles...
I have been thinking of this topic allot being that it seems to be the primary method of forming domes. The compass arm, and how one one chooses to use it, is a direct influence on the shape one ends up getting. Are there any more ideas by you Domies on how one could get interesting and structurally sounds dome shapes?
