“This method of roof construction appears economically powerful enough to illuminate a pleasant path where immortal corporations will unavoidably encounter equal competition from mortal corpuscles.”
It literally took me a minute of rereading to parse this sentence. I do admire their ingenuity though.
Could you do something similar with fiberglass mesh?
Yes. Check the ferrocement site.
Absolutely and its been done in Africa and elsewhere, See yt vid by engineer George Nez, and his book on the topic which can be purchased on amz.
He adds latex to the cement mix, and its called latexcrete. Great stuff, I redid my garage roof with it three winters ago and so far it still looks brand new, impervious to elements, non leaks…I used three materials as test, one was fiberglass mesh, other was plain cotton (old bedsheets), other was cotton poly blend (also old sheets). All are working same so far but the mesh was the hardest to deal with in terms of filling spaces with the cement goop. Mesh is more for covering unsupported spans and it should be woven into two layers per G. nez’s research.
I read this article. Could you please tell what kind of acrylic they combine with the cement. I’ve always been interested in ferrocement building techniques but this is the first time that I’ve seen it used with acrylic vs. shotcrete. I’ll research the acrylic too.
Check this link: https://naturalbuildingblog.siterubix.com/hypar-roofs/ They’re the experts on “roofs first”, hypar roofs and acrylic cement roofs. They sell a low cost book with all the details if needed.
You can use many kinds of acrylic. Including old paint. I have had best success and very cost-effective results using the very thick acrylic (with a bit of silicon added) typically used for mobile home roofs. This can be diluted quite a bit before adding the cement.
Very cool!
