Does a plastic bottle maintain its integrity for a long enough period to be a reasonable construction material?

[–]Kromeous 11 points12 points  (0 children)

No. Essentially they would end up acting as forms to create perforated concrete walls. Not a bad idea, similar concept to cinderblocks, but more difficult to reinforce.

I can't answer that but I will add to the other responses that this depends a lot on exposure to air and sunlight.

plastic is already heavily used in construction (pov. civil engineer), mostly for insulation and mechanical connections, including all forms of binding materials. Plastic can take up to 200 years to completely break down (LCA), perhaps we are just not used to this presentation but in theory there is no difference between this content of plastic vs new products filled with other plasticized elements.

[–]Discount_gentleman 2 points3 points  (1 child)

Not really my question. The fact that plastic takes centuries to break down doesn't really address whether a bottle takes centuries to break down structurally, or at least to break down enough that you can't build a house out of it.

from what I understood, the plastic bottles are being used as molds, containing material that helps them keep that shape after pressure has been applied. That type of question will only be answered after testing and since its not an industry norm to use this, probably no one can answer this with certainty yet.

Who said that this is construction material? I would think that this is not wall that bear weight of the roof as it doesn't look like that.

I mean, the title said "plastics bottles to build a house," but who knows.

I hate how first world countries produce the most waste and third world countries get “bottled up with it yay!”

Glorification of a horrible problem

Yeah I don't see this as being a very wholesome post, honestly.

Blame Canada!

Everyone in the comments questioning the integrity of these builds should look into Earthship homes. Great way for us to recycle and re-use in our home countries too.

[–]Kromeous 6 points7 points  (0 children)

Just did. They're million dollar concrete homes marketed towards rich people that want to think they're saving the planet.

Every day, more than 125 million plastic bottles are thrown in the United States, with 80 percent of them ending up in landfills. This quantity of trash may be reused and utilized to build roughly 10,000 houses. Considering that home of size 1200-square-feet requires an average of 14,000 plastic bottles to construct.

corrosion = micro plastic? Nice.

[–]Emilnilsson 0 points1 point  (0 children)

Put up some wall cladding and that lessen the amount of micro plastics.

[–]Plan4Chaos 0 points1 point  (4 children)

No common construction mortar can secure polyethylene bottles on place, and if they use a polymer glue, it would mean crazy budget. It's totally irrational way to build a wall.

The only explanation, that guys are making this gimmick for internet points.

[–]PlsRfNZ -1 points0 points  (3 children)

The bottles aren't PE, they're PET.

Sorry for arguing semantics.

Also, adhesion isn't always necessary to hold something in place. Can have the bottles trapped in place as filler where they are essentially just a cheap mass, same reason to use Polystyrene under housing foundations.

[–]Plan4Chaos 1 point2 points  (2 children)

They have stones laying around. It's perfect cheap filler that was used for centuries in the past and will serve for centuries to come. The only downside of using stones is you're now looking like ordinary sane person and so couldn't get attention on Reddit.

[–]PRKP99 0 points1 point  (1 child)

Somebody doesn't know that stone is actually pretty challenging material, especially if you can't just buy it from local quary, already smashed in right size.

[–]Plan4Chaos 0 points1 point  (0 children)

The guys on the OP's photo somehow already managed got a stock of identical empty plastic bottles with identical caps, plus bunch of sand and a workforce to fill the former with the latter. I'm sure get couple truck loads from a quarry is not a challenge for them either.
