We've just bought a second hand awning for our new (to us) van, but it doesn't come with a groundsheet. I've managed to source what looks like a suitably-sized groundsheet and we already have a tent carpet that will fit (ish).
I'm a bit concerned that the groundsheet could be damaged by stones on a hardstanding pitch. What is the best (i.e. cheapest that does the job) material to use as a groundsheet protector?
you will find that most sites require the use of a breathable ground sheet, anything under that will defeat the point of having it. on hardstanding you don't need anything under it, it will be perfectly fine
