can you lay lawn over lawn?

[sacbina]

building work has trashed half of our lawn. need to raise level up about the depth of a roll of lawn. would it be really bad to lay turf on top of existing lawn?

(I am assuming answer is yes just because it would be an easy solution!)

It could be a useful solution, but would you just leave the half that is still OK, or expect to re-turf the whole area?

Ideally I think turf needs to be laid on flat, well prepared ground; would you dig it over, rake level etc?

If you only re-turf the damaged area, you might see the result as two different halves, with different varieties of grass, different vigour etc.

I'm no expert; just speculating on possibilities.

would be relaying over the whole lawn, which is not exactly big. would have to rotate it or something as its very compacted

I would think the surface would not be firm enough, as as the old lawn composted down, you'd see a drop in levels again.
