Was interesting until I saw this.
Good for decorative concrete, though.
Around here all the applications of poured concrete are for foundations, basement slabs & walls, as well as commercial building applications.

It goes far beyond decorative concrete. This process can be used for concrete blocks, roof tiles, drainage pipes and boxes, prestressed slabs, and virtually any other product that is manufactured off-site.
For the record, I don't think I have ever seen a basement where the walls were solid pour. It's a waste of concrete when hollow block with poured columns is sufficient.
In coastal BC most places don't seem to have a basement at all.
Twice actually as the first time they back-filled it; the wall partially caved in from lack of rebar (I was renovating an apartment across the street, and talked with the site super on occasion).
it's also extremely time efficient. 5,000 sq/ft homes' foundations can be fully assembled in a day.
It's unusual for you, but you're also not the target market.
I see it mostly advantageous for full-height/walk-out/live-in basements, though.
Recently I was asked to write an updated article and I checked what happened to all those companies. Most of them went nowhere. Unfortunately. It seems to be a very hard problem to reduce the carbon footprint of concrete.
