Liner Choices
Plastic - poly sheet
Difficulty here is getting the width in a single sheet.
Original intention was to use builders DPM which is the thick poly sheet that they use under a building. Its cheap, tough and would be fine for a temporary narrow shallow pool as it comes as standard in 4m wide. To get the required width 6.5/7m my only option would appear to be poly tunnel sheeting which is thinner than DPM hence more likely to leak. Cost circa £80.

Polythene tarp or groundsheet
These are available off the shelf in many sizes. Cheaper ones are pretty strong (laminate) but they puncture easily. By the time you have found a decent thickness you are looking at a vinyl coated tarp which is more costly than at vinyl rubber pond liner.

PVC Pond Liner
These are the cheaper pond liners available off the shelf or made to order quickly. Any seems are heat/factory made hence strong and come with a guarantee. The standard thickness is about 0.5mm. Cost circa £100.

I decided to go with a PVC Pond Liner - mainly to stop any leaking issues (punctures, rips) that would damage the rest of the pool (bales, etc).
