How are the liners rolled out on the jobsite?
The liner roll will be marked (typically on the roll itself and on the exterior wrapper) with the length and width and directional arrows showing which is which. Of course, step one is to unroll the roll in the direction indicated by the first number and arrow. The second number shown is the “unfolding direction”. In theory then, a liner normally can be placed on any of the four “corners” outside of the excavation and unrolled the appropriate direction. Which corner to start on is influenced by wind direction, obstructions present, available room to unroll the liner, and so on. Pretty simple.
