→‎Choosing a lining

* Polyethylene and Polythylene liners typically only last one season.

* Polyethylene will readily conform to any shape, however, it does not have the sturdiness that is required for a permanent pond liner.

* Polythylene, on the other hand, is extremely rigid and can be stiff to work with. Polythylene can be damaged easily by rocks, and has to be handledwith care. If polyethylene is damaged, it cannot be seamed together without expensive welding equipment.

* PVC and PVC-E liners are the next step up from polyethylene and polyethylene, and they can last for up to 10 years.

* Polypropylene is an expensive material but it is the most durable pond liner material in existence because it can last for up to 40 years. Polypropylene, however, is not as flexible as EPDM liners.
