    Firestone PondGard EPDM Pond Liner, 10'x20', 60 mil
    Firestone PondGard EPDM rubber is the industry standard for decorative pond liner. The PondGard membrane is based on ethylene propylene diene monomer (EPDM) synthetic rubber, a highly flexible yet stable waterproofing membrane with a proven performance history in exposed applications. PondGard retains its high flexibility, even in cold weather. It can easily be shaped to fit the unique contours of any pond. PondGard shows outstanding resistance to the harmful effects of ultraviolet radiation (UV), ozone and other environmental conditions. PondGard exhibits a high tensile strength and an outstanding resistance to puncture, and once installed, requires little or no maintenance. PondGard is specially formulated to be safe for exposure to fish and plant life in decorative ponds while resisting microbial and algae attack. It passed both the Environmental Protection Agency (EPA) and the American Society for Testing and Material (ASTM) International test requirements in regard for the safety of fish and aquatic plants.

    PondGard's black color gives a natural look that blends with the algae that frequently grows after several months. The black color also offers greater UV protection while giving the illusion of greater depth. The Firestone PondGard EPDM decorative pond liner features an unmatched quality that has been tried and tested. Create a water feature in your backyard sanctuary with PondGard EPDM decorative pond liner. Made in the USA. Firestone PondGard liners carry a 20 year warranty.

    If you feel at any time your properly installed Firestone Pondgard liner is defective Firestone will ask you to immediately send the questionable section to them. They will fully inspect the material right down to the microscopic level. They will work with you to determine how the liner was installed, if underlayment was used, if roots pushed through into the pond or if the liner was cut or punctured by any foreign object and much more. It is Firestones greatest pride to manufacturer a superior pond liner and every effort will be taken by teams of scientists to determine what caused the failure and how to prevent similar failures by proper installation.

Highly durable: As EPDM is not affected by weather factors (UV, ozone, varying temperatures or frost), the liner is incredibly strong; it won’t crack or split. The greater thickness of Firestone Pond Liner (1.02mm) means that it is more robust than 0.75mm SealEco GreenSeal and therefore has better puncture resistance.
