Background: Old Cavity wall (which had a single door in it), has been removed, ready for fitting new wide french doors. The brick course where the door cill+frame will go has had to be "shaved" by 15mm, to allow the frame to fit (after helpful advice on here).
[Note - on the photo, the bricks look messy, but thats just because the diamond cutter could only go so far. I bolstered the rest, roughly, and will use angle grinder with stone attachment to smooth them off).
The "issue" is that I need to extend the footprint of the floor screed so it comes out to meet the door frame. I am aware that it's important to keep the cavity there, so I can't just go pouring concrete into the cavity (I don't think). My question is, how can the screed be "supported". Basically it will need to extend over the cavity (which is fresh air), so ... whats the best method to do this, and give it the strength it needs ?
NOTE - the shaved bricks are 15mm lower than the inner blocks.
I had (originally) toyed with the idea of a cavity closer, but I don't think that would be strong enough, as it's just plastic. (Also - now the bricks are shaved, it would tilt downward slightly at the door .
Many thanks in anticipation
