I'll be interested to see the responses from the likes of Church, Segs et al - Down here in Dorset, Krend can be picked up for between 6 and 8 quid a bag, but that just about covers a square metre, so you'll be looking at around £1000 just for the mats
Again, never used it so unsure of how quickly it goes on, but if your laying on 40 m a day (estimate) you've got 4-5 days inc rubbing up
I would have thought a couple of grand but I may well be miles off - Like I say, Church & Co should come up trumps
