Sand School membrane

[lisan]

Anyone give me a rough idea of how much it would cost for membrane to do a 20 by 40 arena?

Thanks

Can't remember exactly but we used three rolls for a 20 x 60 and it was about £250 a roll I think.
I found ours by doing google searches and bought straight from the manufacturers.

Do you really need a membrane? Lots of people don't use them anymore, we haven't got one on ours.
