Quote ="knockersbumpMKII"they reckon it was £125k a couple of years ago to relay wembley but then they relay it a few times every year. not sure how the £1M figure for Leeds was worked out as Old trafford's was quoted at £500k this year. done by Desso, a Dutch firm.'"
I think the price difference depends upon what they are actually doing. i.e. a relay of turf on an existing base layer is going to be cheaper than removing all the existing tuft & base and effectively starting again from scratch, which is what is needed in some cases.
