Pond Liners & Underlayment  (52 Pond Liners & Underlayment)

Pond liners are the perfect way to create custom water features, ponds, and water gardens. With many liner options available, you'll be sure to find the liner that best meets your needs. Firestone EPDM PondGard liner exhibits a high tensile strength and an outstanding resistance to puncture. It's offered in both 45 mil and 60 mil thicknesses and will retain its high flexibility, even in cold weather. Premium PVC Pond Liner is offered in a high-tech, lightweight design that resists both tears and punctures. Its easy maneuverability and 20 mil thickness is perfect for the home installer. Both EPDM and PVC liners are fish safe and carry 20 year warranties.

Smaller liner (under 150 lbs) can be shipped via UPS or FedEx, while larger liner must be shipped via Truck. For Truck delivery rates, add your liner to your shopping cart, enter your address information in the first step of checkout and you will be given Truck S/H pricing. If you have any questions, please do not hesitate to call us toll free at 877-562-1818.

To calculate required liner size, determine the rectangular size of your pond. If your pond is irregular, determine the size rectangle in which your pond will fit. The liner size your pond will require can be calculated as follows: the planned width plus twice the depth and 2 feet for the edges and the length plus twice the depth and, again, 2 feet for the edges. For example, if you wish to build a 10' x 15' pond that is 4' in depth, you would need a 20' x 25' liner (10 + 4 + 4 + 2 = 20' wide; 15 + 4 + 4 + 2 = 25' long).
