We're new to motorhoming. We've just bought a secondhand driveaway awning but it didn't come with a groundsheet.
Doing some reading up I discover that some campsites only allow awnings if you have a breathable groundsheet, I presume they mean something like this.

I have two questions.
1 - If these groundsheets are woven and breathable I presume that they are not waterproof, is this correct?
2 - Why do camp sites insist on breathable groundsheets for awnings, but not for tents?
Tents have to be waterproof underneath to sleep in them awnings don't unless you want to sleep in it, In which case an inner tent can be hung in it which will be waterproof underneath. A breathable groundsheet should be used if waterproof item is not required as grass should revive quicker once pitch is cleared.
They do work,after 2 weeks in Cornwall the white around the edges is where the mudflap was and the square is where we had a mat.The tents on the same site killed everything and just left mud as we had heavy rain at times.
Yes the water does come through the holes and some people on site before us had put plastic sheeting under the groundsheet as it was so wet but this left everything dead and very smelly.The rain was very heavy at times, possibly the worst we have ever had but with normal rain and a well drained pitch the ground will dry out quickly, we just leave the top of the awning fronts open for ventilation. We always take some rubber backed matting offcuts just in case it does get bad, being a carpet fitter means a good supply.
