How are pond liner sizes determined?
Good liner estimating is the proverbial “art and science”. Like a lot of things, the more you do it, the better you get! Generally speaking, it is important to keep foremost in mind that you are dealing with rectangular panel shapes. Obviously, most of the time ponds and pits are not rectangular. So usually there will be some degree of waste involved. There are various ways to reasonably minimize this waste, which everyone appreciates. Another big factor to consider is whether or not the installer is capable of cutting off and then reattaching corners, joining rectangle together into an “L” shape, etc. This will always go a long way in minimizing waste. If this is not an option, basically one must just get a rectangle large enough to cover everything that needs to be covered and cutting off the excess. Again, the more the pond shape varies from a rectangle, the great the percentage of waste. Getting skilled with a hot-air or hot-wedge welder is a HUGE plus.
