It's perfectly possible to lay turf on top of turf, at least in our relatively
high rainfall area (Forest of Dean). We have used this to level a sharply
sloping lawn. We got the turf from creating new flower beds from the lawn in
another part of the garden. The turf which we cut was at least two inches deep.
That meant that it was able to care of itself (perhaps unlike some commercial
turf which is much thinner).

Even with thinner replacement turf, if you place soil on top of the existing
lawn (and firm it down well and level it) then place the new thin turf on it,
the new stuff will have something to root in to.

Do NOT put a geotextile over the existing lawn. These fabrics are useful
because they prevent things rooting through them, which is the opposite of what
you want.

One last thing. The thinner the turf you lay, the more you will have to attend
to watering. However, in our experience, grass will grow more or less anywhere
and anyway, whatever you do to it.

Good luck with the new lawn !
