I debated putting this somewhere in building, but decided here was more fitting for two reasons. First was that there wasn't really a category that quite fit it there and second was the fact that it isn't exclusive to creating buildings. I know this material can be a bit pricey, but it also has a lot of possible advantages for projects around the homestead. I could see a lot of value in having a way to quickly build concrete structures in 24 hours out of a material that starts out flexible. Does anyone have any experience with this material?
Not sure what this stuff is, but the name reminds me of the two cabins I built in Georgia with old carpets stuccoed with cement. The result, with a little tweaking (mix the cement quite soupy, and wet the carpet with soapy water ahead of time to improve adhesion), is a rigid surface conforming to whatever shape the frame underneath is. The roof of the first cabin was framed in pine poles and bamboo, and had a deck of two thicknesses of cardboard and plastic under the carpets. I once had five people on that roof at once, and it never leaked, not in ten years. I began to refer to old carpets as the modern scrounger's equivalent of buffalo hide.....its flexible, durable, and so useful for so many things......
It is sometimes also called concrete canvas. If you pull it up on youtube, they have a number of videos of how it can be bought as prefab buildings or some of it's other uses. One of the sites for it is located at http://concretecloth.milliken.com/Pages/home.aspx and details the basic nature of the stuff along with some of its usages. Sounds like the stuff you mention is a pretty solid home-made version of the same thing.
PRICEY! You are paying a lot for the instant "just add water" convenience.
