I would think that the membranes would also be the reinforcement. Though I am not getting a good picture in my head from the description. It has to be practical. Mix concrete, pour concrete...the same way we do it now. There is roomm for skilled labor at the reinforcement phase which is a precision bit of construction that is inspected closely before pouring.
