I would call that a feature. Building forms is basically building the entire building out of wood (or metal), then building it again out of concrete. Single family homes or multi-unit low rises don't require low void high compressive strength. They need speed. Residential prefab never caught on in North America. Maybe this will. If it is cheap.
- Animats 5y agoResidential prefab never caught on in North America. True. Neither did concrete construction for residences. Edison tried it. He had a set of concrete forms that latched together. Then you poured concrete, waited, and remove the forms. It was never popular, but there are still a few left in use. I live in a cinderblock house reinforced with concrete and rebar. It was built around 1950 by a commercial building contractor, as his personal residence. The interior is quite nice, but the exterior looks industrial.
- ThrustVectoring 5y agoThat's why I have a lot of respect for Insulating Concrete Forms. You build it out of polystyrene insulation, then fill the voids between the two sides of the form with high-compressive-strength concrete. No need to tear down the form, no need for an extra step insulating the thing after you've built it. That all said, it is somewhat more expensive than traditional construction. Better insulated, more energy efficient, and more resilient to fire and flood.
- galangalalgol 5y agoWhy didn't residential concrete ever take off in NA? I was talking with a builder in the Netherlands and he the stick and drywall used in the US is only for temporary buildings there. Also, all the concrete and masonry residences I see in the US have cracks everywhere.
