Block would have been ok, but he should have used a stainless "starter"
strip. That fixes to the existing wall, and is then tied into the new
blockwork as it is built. Its a strong and accepted way of keying new
stuff to old.

There's something in there, but not at the top block (cos I can see right
past that), but it's not protecting it much against torsional loads on the
end.

Don't know if it's installed wrong, but I could get +/- 0.5cm movement out
of the column light hand pressure. Heavy hand pressure would have got
more - certainly felt like I could have broken it off it I wanted.

When I've got the acrow in I'll see how much it takes to actually break it.
I certainly can't accept 1/2 the horizontal bonds breaking and the entire
vertical one showing light through - especially on a lintel support.

Cheers
