Hi gregers and, once more, Tony No time to reply until now but much appreciated. No doubt the joist's deflected to some extent over time but... nothing's dropping off underneath, all seems sound enough and acceptably flat; to my mind the grief of deeper intervention well outweighs the...

Big thanks to everyone who made suggestions - very helpful, much appreciated. Existing plumbing gone to allow equal bracing each side of the joist. All floorboards already spanning the joist and its neighbours will be left well alone. Ply and steel sourced, cut, ready to drill. Next...

Good point on the chequer plate, local engineer suggested it as he has plenty of offcuts, although he currently holds no flat 3mm & would have to buy in a large qty of it for my relatively small job, no point. But maybe I can source some myself. Compared with the fabrications he knocks out, my...

Thanks mfarrow To my eyes the joist is not noticeably lower than the neighbouring ones, I think in this case it's more that over time the plaster has given along the line of the joist as the load has fluctuated (+/- one person & bathwater) It's difficult to judge as plaster and lath seems to...

Hi Lower, thanks for your suggestions which zero in on what I think I'm going to do. Good call on bulking out the notch prior to resin, I'll have to see whether that stuff can be bought in smaller quantities. Not calculated the exact volume but it's not far short of a litre which is the...

Thanks also to Porque 223 and rjm2k I see the different ideas all circling the same problem... @ Porque - I see what you're saying, your scheme would require both intervention through the ceiling and also applying an upward force to counter-deflect the joist before packing and reinforcing...

Sorry didn't reply earlier, was out scrounging a bath :) @ Tony - many thanks for taking the trouble to sketch that idea, simple=elegant compared with my own side reinforcement. The notch is indeed under the bath; I've 300mm to the right to play with remaining in the bath's 'footprint', to...
