| Polthyelene | |||||||||||||||||||||||||||||||
| This material is inexpensive and most hardware and home supply outlets may carry it. Low density polythylene is acceptably durable, but avoid high density polythylene either can be still in cold weather. Polythylene is difficult to repair. Last about two years in a pond and will last longer where it is not exposed to the sun. Low burst resistance, difficult to install and has no elasticity. | |||||||||||||||||||||||||||||||

| PVC (Plastic Polyvinyl Chloride) | |||||||||||||||||||||||||||||||
| These liners are relatively inexpensive and available with or without nylon reinforcing. However, they are easily torn, they do not hold up to colder climates, they are very susceptible to the detrimental effects of ultraviolet light and they have a relatively short life span of four to five years. PVC for swimming pools and roof can be toxic to fish. PVC-E is an imporved version for fish. Can be repaired and economical to buy with some brands could last 10 to 15. | |||||||||||||||||||||||||||||||
| LDPE (low density polyethylene liners) | |||||||||||||||||||||||||||||||
| PVC is a good buy, but it has been over taken by more modern LDPE it offers an economical alternative to PVC. They form to the contours of an excavation more snugly and rarely produce significant wrinkles if folded boldly at the corners. Economical to buy and can be repaired and has long life. | |||||||||||||||||||||||||||||||
| Rubber liners are more flexible and easy to form of your pond and are not susceptible to UV light degradation and it is long term guarantee for ten to twenty years and a projected life expectancy in excess of forty years | |||||||||||||||||||||||||||||||
| Butly (Isobutylene Isoprene Rubber) | |||||||||||||||||||||||||||||||
| EPDM ( Ethylene Propylene Diene Monomer) | |||||||||||||||||||||||||||||||
| Some EPDM use of oil fillers which contaminate the water and will kill the koi. Make sure when buying its made for pond. This rubber does not contain any butyl, it has same specification and is ideal for any pond sixe. The only drawback are it cannot be box- welded and butly tape will not adhere to its unless surface is first prepared with petrol and keyed. It is ideal alternative to butyl. Very durable more expensive. Look for EPDM-SF which is not toxic to fish | |||||||||||||||||||||||||||||||
| The liner are available in almost every conceivable size in pre-packed form or off the roll anc can be tailor made on-site vulcanising for larger installations such as lakes and reserviors. For the dicerning koi keeper who does not want to see any pleats or fold, the liner can be box welded to your specification but expensive than buying it as a flat sheet.
