Save time and money with the EasyPro DuraLiner Pre-Cut and Boxed EPDM Liners. Each liner comes ready to install and creates a finished pond at approximately 24″ deep.
Whether you’re building a small backyard water garden or a larger koi pond, DuraLiner™ offers reliable performance for every project.
Made from 45-mil EPDM rubber, DuraLiner™ remains flexible in extreme climates (−40 °F to 175 °F), resists punctures, and will not crack with age or sun exposure. Manufactured with first-quality virgin resins, it meets ASTM D7465 (Type 1) standards for strength and durability.
The material is fish- and plant-friendly, simple to install, and backed by a 20-year limited warranty.
