building ping
"Satan / Cheney in "08" I wonder if it would stay dry in the rain?
Tagline space for rent.
Only if you ordered the optional roof. ;)
"Satan / Cheney in "08" its a very excellent idea.
Revelation 6:6 And I heard a voice in the midst of the four beasts say, A measure of wheat for a penny, and three measures of barley for a penny; and [see] thou hurt not the oil and the wine.
I think so as well. When you see the distances building material is trucked to locations, say, like Tyvek, or lumber from Canada, all across the nation, it seems absurd. Seems to me the best material for the gross construction is dirt or rocks from the site. Not to mention the most excellent insulating properties that 15" of sand has.
"Satan / Cheney in "08" Red, just last week we had a new roof put on our tar and gravel ancient roof that was well past its time. Leaking etc. The crew put a dense foam (4X8) sheeting on the roof, maybe 1" thick, and the heat sealed a Buytal 50 mm bright white sheeting on top of the whole thing with flashing and overlapped the heat seams about 1 1/2" Already we can tell a great difference. The store is warmer in the morning and, before the new roof, around 11:00 you could feel the heat radiating in from the sun. The roof was $7000, and I know the payback in terms of less power to cool our products will be long term, but already it has provided for a nicer environment for us, and that is something I really did not expect. Much cooler in the summer and warmer in the winter, not a bad plan. And we had to do it as a few years from now the joists would be laying on the carpet.
"Satan / Cheney in "08" you see Tom, construction is my real profession. it is a very interesting way to build. At first I thought the sandbags were just an expensive insulation with no structural value. But the way it is configured the sandbags may well play a structural role. Because you see those vertical wood & steel components spaced 3-4 feet from each other are likely in themselves not strong enough to hold up a roof. If the sandbags are actually pressing against each component on both sides, then they're serving like a constant lateral brace all the way up & down. That would add a lot of structural strength to the vertical wood & steel components. So, I don't know if the sandbags are structural or not. at first I assumed they'd put some sort of sheathing on the outside of the building and screw it into the wood & steel vertical components and that this would beef up the structure tremendously. But those sandbags are sticking out beyond the wood on the outside, so I don't know. Maybe they'll just spread a stucco or adobe type mixture on the outside of the building to finish it. Those sandbags would make a great lath. I've long thought that compacted soil can be a great building component. The soil itself has great compressive strength, and then if you use post-tension steel or other steel to provide the tension to hold it together, I bet it could work. The sandbag uses that same concept with the sand providing the compressive strength and the bag providing the tension. Believe me Tom we can build buildings a lot less expensively than what typically happens. Anyone who tries to innovate in the construction industry frequently gets squashed. Some innovations have come along the last 30 years, not many though. In the construction industry our productivity growth rate numbers are frequently negative, not positive.

I knew that, and your post is prophetic. I have been in "earthships" around NM, that use old tires and compacted site dirt to form three foot thick walls for the structures, and the effect from the four or five I have been in was nice, With that kind of insulation the internal temps hardly vary from day to night. I suppose it is a above ground cave. Then there is the lunacy of me, in Colorado, for seven months at least, I pay to run a refrigator in my house while I pay to heat the house while their is massive lack of heat two feet away. We can be smarter than this.
"Satan / Cheney in "08" I am not in the industry, but so many times I have seen the bitter cold winds of winter scour houses here and wonder why the plan didn't use north east earth embankments to insulate the structures.

My first thought when I saw it: The African version of straw bale sonstruction. I think about straw bale a lot. Once when we had all these sand bags lying around after a bad storn, I got to wondering if you could build a house out of them. Now I know!

I was raised in the construction field. If I really wanted to, and could get around the code, I could build a decent house for $10,000.
Would it involve a stump? Seems like an upside down bass boat could make a great roof.
"Satan / Cheney in "08" I have been in several straw bale houses................They were great. Stick and gyp need a model replacement.
"Satan / Cheney in "08" Sandbags rot after a few years.
it depends on the material used for the bags. and for some materials it will depend partly on whether or not it gets wet over time.

Next time I have to go to Windham, NY I'll take pictures of a pretty unique building. It's made out of split firewood.
I shall not vote for evil, lesser or otherwise.
I have been in several straw bale houses................They were great. Stick and gyp need a model replacement. That's great to know. My cousin, who is a contractor in Vermont, had to take one down for a customer, because of the mold problem. That's a problem that I think has been addressed since then. I first got interested in straw bale while reading my daughter The Three Little Pigs. When I got to the part about the straw house, I looked out the window and spied the straw bale left over from Halloween, and wondered Why couldn't one build a house out of straw bails? Shortly after that, I ran across an article that said people had done that in the Midwest a hundred years ago. I've had an interest ever since, and collect articles here and there. I have one magazine that talks about a woman who built a studio away from her house out of scrap materials and straw bales for $400. I think she applied concrete to the outside by hand. In retrospect, she said she would pay someone to spray on the concrete. I want to build a little straw bail get-away-from-it-all house with a rubber and grass roof, somewhere one is still free to do with one's "private" property what one wants, without some bureaucrat crawling up your behind every step of the way; don't know if there is such a place at the present time. Some day.....
