Carl,

In all things architectural you need a structural engineer as a consultant
to assess the danger of the current situation with the degrading bricks and
to also help draft specs for any stabilization / restoration work that will
meet all applicable building codes, etc. There are ASTM standards for bricks
for construction and even if using reproduction or vintage bricks you may
need to meet that standard. Usually with soft degrading bricks there may
need to be a combination of structural support along with some replacement
with bricks of the same size that match color and texture. Each situation is
unique and there is never a recipe you can follow that applies to all
situations.

Cheers!
Dave
