Product Description

45 mil EPDM rubber pond liner DuraLiner boxed sheets deliver a professional foundation for building a reliable, finished-looking pond with fewer seams and easier handling than full rolls.

Built for demanding pond environments

Designed for water gardens, koi ponds, streams, and decorative water features, this liner uses 45 mil EPDM rubber and is engineered to stay flexible across wide temperature swings (from -40 to 175). That flexibility helps the liner conform to shelves, curves, and contours during installation while maintaining long-term resilience.

The material is described as puncture-resistant, weather- and UV-resistant, and formulated to resist cracking with age. It is also noted as fish and plant friendly for typical aquatic use. The liner meets or exceeds ASTM D7465 (Type 1) technical specifications and includes a 20-year limited warranty.

Why choose a boxed, pre-cut liner?

  • Faster installs: Pre-cut sizes reduce layout time and help minimize seams compared with piecing multiple sections together.
  • Cleaner finished look: A single sheet is easier to position and fold neatly into corners and shelves.
  • Easy to form: The EPDM construction makes shaping and detailing around rocks, edging, and skimmers more manageable.

Performance highlights

FAQ

Will this 45 mil EPDM rubber pond liner work for koi ponds? Yesit is listed for koi ponds and described as fish and plant friendly for aquatic applications.

How do I select the right size? Choose a sheet that covers the full length and width of the excavation plus depth and overlap at the perimeter; when in doubt, size up for easier edging.
