What is preferred, rubber liner or a hard shell liner, and how can I tell what size to buy?
By far flexible rubber liner is preferred over hard shell liners. Rubber liners offer the independence most water gardeners demand. Preformed hard shell liners are far more work and less rewarding over the long run. Renck’s Garden Center offers a highly durable rubber liner constructed of a 45 mil EPDM. There is no better way to assure an easy to build, long-lasting, and puncture resistant pond than using the 45 mil liner which is guaranteed for 20 years. Hard shell liners tend to be aesthetically as well as artistically restricting to the pond owner. In order to determine the right size of liner use this formula.
