looking to put a floor deck into my garage to make a storage space above it. One end of the joist will be resting on top of a dividing wall, the other has to get support from an existing double skin engineering brick wall, higher than the joist level. I think my choices are thus:
Masonry hangers
Bolt a timber onto the wall and use timber hangers
Cut holes in the wall and rest the joist ends on the brick
I haven't seen anywhere that says masonry hangers can be used on an existing wall as the advice seems to be that they're built in when the wall is going up, so I think they're out. I'm leaning towards the bolted timber route, but it may also be relevant that the mortar in this wall is lime and pounding it with a large sds drill does loosen the brick slightly in places like where windows and doors have been installed. Hopefully this would be less of an issue mid wall
At some point in the future, I'd like to widen a 1m doorway to 3m, underneath where the joists will hang, if this has any bearing (excuse the pun). There will be a metre or so of brickwork between where the joists attach and the lintel for the door
