what is the landscape fabric made of?

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?

depends upon what kind of grass you are covering.
we've used the standard rolls of the stuff and don't
have any trouble with grass coming through it, because
we overlap the edges some, roll them together, pin
them down and then cover with a fairly thick layer of
mulch or rinsed crushed limestone.

if you suspect you have very difficult grasses that
can push up through your fabric then dig it up and
remove as much of the grass and roots as possible
before covering. at least then you are removing some
of the energy store available to the plant.

most failures i've seen in mulching and ground
fabric is when people skimp on the mulch or they
don't do the edges right so things come in from
the sides or seams. if the fabric is exposed to
the sun it will eventually degrade.

in your specific case, i'm curious about how much
sand you have blowing around there? because if you
do have enough sand being moved on the winds putting
down weed barrier and then a gravel mulch on top of
it won't work for long, if it gets buried by sand...
