Sound. But see my earlier reply.

Turf won't stop weeds coming back up through, but
putting the membrane back down before turfing will help in this
respect.

I really don't think I'd lay a membrane under turf. The little grass
plants want all the access they can get to the soil. Modern turf in
particular has very little soil attached, and I think most of it
would die in the first dry spell even if it had managed to get a bit
of a toehold. Weeds aren't really as big a problem as all that,
anyhow.
