Pond Liner

The Protopond.com Pond Liner collection brings together flexible pond-lining materials for creating watertight ponds, streams, waterfalls, and recirculating water features. Flexible 45-mil EPDM is a common choice for shaped excavations because it follows shelves and curves while tolerating outdoor conditions. For each direction, add twice the maximum depth to the finished length or width, then include extra material for anchoring and irregular contours. A 10-foot-long pond that is 2 feet deep needs more than 14 feet of liner once edge allowance is considered. Remove sharp objects and place compatible underlayment beneath the membrane. Review specifications before ordering.
