Neat.

Based on the production techniques, looks like this is pre-fab only kind of product.
I wonder how durable the water repelling treatments are? How they cope with icing?

Any ideas for field applications? Home basements would be cool, but unlikely. Parking structure?

No different than current prefab. Most of the issues they are trying to solve can be solved other ways currently. It would save some money, perhaps, but the current limitations on prefab will remain, mainly transportation costs and need for experienced trades that have worked with prefab before (prefab required the previous trades to place their work accurately or there will be costs associated with field corrections that lose the benefits of prefab speed).

Now if the new concrete can be cast-in-place, that would speed up construction, and perhaps reduce the need for insulation and waterproofing.
