Turf on top of turf
 

I stay in a new house and the builders are going to put drainage in and returf the lawn. Problem is that it looks like they are preparing to put the new turf on top of the old turf. They have already put the sand down. Is this a problem? Please answer asap the coming back tomorrow to finish.

Not a problem. The old turf will just decompose and feed the new turf.
The way most contractors work around here, you probably also just
doubled the amount of loam you have. Be quiet, nod and smile before
they change their mind. Just my $0.02...

Err could be I’m afraid ! That’s just going to mess up the drainage they put in and create a pan layer! After a time when the old turf starts to brake down it will also make your lawn soft and sponge. Not the best but its up to you.

Just do a web search for how to lay sod. I think you'll quickly find
that the right way to do it requires properly preparing the soil. And
just laying new sod on top of whatever is already there isn't one of
the accepted methods. A little work upfront to do it right will avoid
either total failure the first year, or years of trouble ahead.

I'd take pictures of what they do, so when it fails, you have good
evidence of why.

I've never seen such a thing in Ohio.

One of the big problems may be when the old turf starts to decomp and
it creates quite a bit of heat. You could be setting yourself up for
burning the roots of the new turf. Not only that, but it will be much
more difficult for the new turf roots to grab hold of the soil and take
on water. If you are going to replace an entire yard of old turf -
whether with seed or sod - the best solution is to kill the existing
turf first, cut it down as low as possible and then if you are going to
sod, till the whole yard. If you do not have an irrigation system or
hoses in place to keep watering the new turf you stand a good chance of
losing the whole thing.
