Should I be worried about this

The plumber channelled out a track in the wall for two heating pipes going upstairs. The track is deep into the 100mm blocks.

I looked above and saw padstones and steels and got worried we have undermined the structure. So in panic, I added those straps as a band aid.

How should I proceed to make this stronger? Short of taking out the pipes and rebuilding the wall...

Vertical chases should be limited to 1/3 depth of the masonry unit.


I'd run it past your engineer but it's unlikely to have undermined the support for the padstone.
 
Why are you bothering, the load is all downwards...gravity and all that , the joists are just pocketed into the wall. The padstone just needs a column of blocks under it... There is little lateral load, the wall to the padstone side is a pier...see below

That works on none-windy days and when the internal and external temperatures are exactly the same every single day of the year. We won't mention seasonal ground water changes though.

What exactly are foundations for ?? to take account of the soil structure and its response to changes in temperature and moisture...why do you think we stick them down in a hole..why build a raft in clay soils. Windy days on an internal wall got to be some bean eating going on.

Slender masonry columns are not a good idea.
Thats half of all new build garages out then, the ones with a slender column supporting the over garage bedroom....piers are used all over the place..just take a short walk down any high street huge expanses of glass with a narrow pier unconnected in the middle.

A single column is used in loads of applications, it just a matter of the load on it, ie the 4 brick column found in lots post war semis, supporting the big two bay windows upstairs and down plus the roof above. and they were removed once steel became available for windows.

You said all the loads are vertical. They are not.

Foundations are designed for an evenly distributed load, not point or part loads from individual wall sections.

Wind load on an external wall that an internal wall is tied to affect the internal wall.
