Hi Songbird,

Don't know yet. Still talking to the contractor.

The concern was the chemicals to use on the fabric
in manufacturing. "Apparently", some take about a
month to break down before the fabric becomes
permeable.

Would you tear up the grass or just put the fabric on
top of it?

When we built our raised bed gardens we put the fabric on top of the
grass. Fabric killed the grass but the nut grass grew right up through
it. We're still digging and pulling nut grass out of the beds but we
seem to be winning the race. YMMV
