Bottle Bricks in Africa — 16 Comments

  1. I want to know about the cement bonding characteristics with the bottle’s smooth surface. Also what other disadvantages are there?

    • The bottles should bond adequately with the cement because there’s a continuous lattice of cement mortar. The main drawback is this method uses a lot of cement.

  2. I think this is wonderful and workable idea…just need details on how to hold bottles together. I like in the desert and sand is plentiful…just fill the bottles once a week and stack. Always open to new ideas to recycle.. Jeri Sue

  3. Those walls are beautiful and the workmanship looks impeccable! Have you seen that the folks at Project Somos in Guatemala are using bottles for their interior walls? They are stacked vertically between wire mesh which I assume they will plaster. I can’t tell if the bottles are filled with anything by the photos. It’s a neat idea that we’re considering for our internal walls because plastic bottles litter the streets here in sad abundance. I’m just wary of the chore of filling of so many bottles…

  4. I believe a better system would be using a recycled soda filling machine modified to fill the bottles with a geopolymer product. Simple bricks could be made by the millions..

    • Yeah, it would be very slow. Much faster to use earthbags. Use recycled rice bags, etc. and the end result would be about the same: low cost, local soil, low impact. Bu you’d save time, and tamped soil is stronger than loose soil. Earthbag would be less expensive because you don’t need cement between courses.
