very similar to what i did Damian,only that i propted the floor up underneath to stop sagging with wooden sheet and used a jack to support it then in turn after injecting the solution in the holes i plugged them up with wooden dowels then when finished injecting covered the area with plastic sheet as the glue does not stick to it then applied pressure to the floor to keep it flat while drying this worked very well on my floor ...good luck and take your time Andy
