Wouldnt the tie wire allow rust and damp to travel through to the reinforcing?

Why use tie wire anyway?

We mostly use 'C' Rings now. The composite is different from regular mortar. Very few open capillaries so it doesn't wick water. Dense vapor proof shell mix except for the added closed spherical cell aggregate. 2002 wet samples show that rusting is halted in the shell and even protruding steel. The aeration interferes with progressive rust by providing closed micro voids for some rust to occupy in a dense surrounding matrix. Stops micro cracks and pathways for more water and air reactions.

@ShambhalaVillage It's fascinating stuff. I'm used to pouring concrete footings and then struggling with back breaking concrete blocks. This looks far more sensible :)

There are thinshell version of each concrete design-sidewalks, curbs...all many times more durable, easier to repair, and much less volume to handle. Change is slow due to the outdated methods and architecture being well established within the commercial housing/banking industry. New construction technologies better serve small business that can be paid employees of clients instead of contractors. Otherwise, state restrictions make authentic sustainable solutions only novelties for the rich.
