I have old oak flooring *that's laid on a floor that's 3/4" off the level. I
want to lift the oak off,level the sub floor & relay the oak. Anyone know of
a product that I could pour & then nail thru to relay the floor?

There are some "no shrink" grouts out there that I have used in the
concrete trade. I've set 50 ton concrete walls on a 2" pad placed on
a regular footing.
As far as nailing the oak down, we had simular situations.
We would drill a 1/4" inch hole and fill in with a 1/4" dowel, mark
the hole and then place the wood and nail into the dowel.
One trick is to keep the hole at a certain distance (off of the
previuos piece) so you dont have to "hunt for it.
