We started off with the spongey green mesh but in wet conditions it did tend to soak it up and stayed wet for a while. We now have Isabella Bolon grey plastic breathable groundsheet instead, it's not cheap but it is hard wearing, should last for ages and doesn't soak up moisture.

Moroccan Mats...interwoven plastic. Air permeable and strong. We bought ours at a show, and many sizes are available. Had ours for years now. (2209) So hardwearing also. Only thing is they are difficult to fold down to a small size.
A day of all things motorhome and campervan. The show is held both in the main indoor arena and across the grounds. Catering, hot drinks and food options are available. Easy access to the site and free parking included. Win one of five pairs of day tickets
