Fake grass?

[CharlesRyder]

Can we lay this on top of flags? How do you stop it sliding around, does it have to be pegged down?

We are letting our house and have a very rough area of flags/ dirt which we used as the 'dog area' of the garden. I think it would look nice with some fake grass on it but is it practical. It would be quite expensive to be wrong?

The alternative seems to be gravel but I don't think that would be as nice for the tenant's children.

No idea about laying it easy maintenance, looks good etc but someone told me it wears badly -- so maybe not a great idea if tenants will have kids who will wreck it?

It needs proper drainage underneath. You can't lay it on top of flags.

Thanks burnished.
