Nailed, or sometimes epoxied.

I once had a house with a solid floor where the carpet bar had
obviously come adrift having been glued down. The previous owner
had just put a long screw through it, but this appeared to have
penetrated a damp membrane, so a bit of digging out and epoxy
dribbling was called for.
