reflection, this would be an innovative solution for retrofit
reinforcing of a un(der)reinforced wall which was below an existing
floor where there was no access to put a full length of rebar in from
the top or sides, and an internal stiffener was impractical or would
require expensive changes to fixes or loss of business use of the area.
The placement would, indeed, be somewhat problematic, but with a high
lift grout measured by patty size and a bit of vibration, you could
probably expect a roughly vertical drop of a sufficiently heavy chain,
especially if it were placed with a weighted end - say a bar with a stud
or two - in 1-2 courses of grout for an initial set, then lifted taught
for grouting.
It would take a special application for this to be cost effective, but I
can see how there might be a significant savings over invasive
reinforcement techniques.
