The liner arrived today, 40 x 50 ft and 590 lbs. I have a crew coming in the morning to get the liner in and I am paying them by the hour so I need to figure this out in advance. It looks like it was folded and rolled, and the long side is on the roll. Access into the pond is on the long side of the pond. If I unfold and roll it into the pond from the long side, it will be in the pond the wrong way. The seller's only suggestion is to unroll it and then once it is in the pond, turn it around, or unroll it completely next to the pond and then drag it in. Any suggestions? Thanks.
