Quail Springs’ Focus on Permaculture — 6 Comments

  1. Except for the bottom 3 courses, all the bags in my house are filled with ¼” crushed limestone with dust. No cement whatsoever. They tamp solid and will last as long as any cement mix. Cement is unnecessary.

  2. Hey Kelly you just proved my point the one building you pointed out that you built that you believe will last centuries is made out of volcanic rock I rest my case

    Remember pumicecrete is not for everyone there a few good alternative building materials that will work and that’s fine all I am saying is that if you want the best most insulated and most big bad wolf proof home on the planet nothing beats Pumicecrete

  3. Show me a 2000 year old cob home but there is a whole city in Italy that is built out of pumice and the buildings are still standing!!! This city is Rome the Colosseum the pantheon the aqueduct the bath houses seaports iand sea walls to be under salt water for 2000 years still standing today all made out of pumice can you build a ceiling or a floor out of cob can you build a shower out of cob can you build a hot tub out of cob can you build countertops out of car yeah yeah but Pumice is way better and only takes three materials pumice cement and water in the ratio is 10 to 1 ithas a very low cement content and you can use a lime based binder which uses a lot less energy to make there is nothing that even comes close if you want to build the best home on the planet Pumicecrete is your only choice nothing even comes close will your building material last 2000 years mine will

    • The Great Wall of China was built nearly 3,000 years ago with stone, brick, tamped earth and other natural material and is still standing. The Egyptian pyramids were crafted of stone even before that. I built my earthbag house with bags of scoria (like pumice, a volcanic stone) without Portland cement and I expect it to be around centuries from now. I like pumicecrete and feel it has many worthwhile uses, but it is not the only reasonable choice.

    • Pumicecrete has its place, but it is difficult to make the case that it is better than cob or other earthen materials. Pumicedrete does use Portland cement, an industrial pollutant, and the pumice is only available on a local basis in few places, so it has its problems in terms of sustainability.
