Restraining column against existing wall

[NandM]

My SE has specified the use of Ancon SPB or similar farme cramps to restrain the new steel column with the existing wall. 

 

It fairly clear how this would work with the new block wall, but I can't see these being useful with the existing, unless I need to scrape out and then re-motar? 

 

What other alternatives are there? A simple option I can think of is the use of masonry framing screws, or for something more robust resin some bolts through into the wall.

Ask the SE.  It is their job to specify correctly.
