Prices for bags keep going up. What isn’t? Here’s one more possibility for readers who can’t find affordable or recycled bags in their area. Paula, one of our readers, sent us word of what they’re doing to cut costs in Brazil. “People are getting together to buy a big quantity of rolls for hyperadobe and it’s going to cost around US$550 for a roll with 1000 meters. Cheaper if they can get more people interested.”
Owen’s back of the envelope estimate: 1,000 m. = 3,280 feet. Typical bags are 30” long, so that’s roughly 1,300 bags after deducting 12 bags to make seams, which means single bag cost is around 42 cents. Hmm, that’s still pretty high in my opinion. But the basic idea is still a good one and should lead to the lowest prices in your area. [Note: mesh material is most often used in tubes to make hyperadobe. I’m making the conversion to bags just to see how it compares to bag prices.]
