Ground sheet

Hi all,

I'm looking for something to use as a ground sheet which will ultimately cover the entire ground under the 4wd and a meter or so each side, except for the passenger side where I want a couple of meters so under the awning is covered.

The most obvious choice is shadecloth as it will fold/roll down to a small foot print for storing inside the 4wd but I was wondering what other suggestions you had for me?

I remember reading something about a material used for helicopter landings that allowed sand to fall through it ... can anyone tell me what this is called?

Also, just fyi, we had a roof top tent on the 4wd so we walk around the 4wd quite a lot, especially under the awning on the passenger side and the rear to access the fridge and drawers.

Cheers,

Jason.
