DuraLiner™ 45 mil EPDM Rubber Pond Liner Roll
Full rolls of first-quality 45 mil EPDM rubber in 18 sizes, from 5' x 100' stream runs to 50' x 100' sheets for large ponds. Flexible, fish-safe, and UV resistant.
DuraLiner™ is made only from first-quality virgin resins, and every roll meets or exceeds ASTM D7465 (Type 1) technical specifications. EPDM rubber is easy to shape around shelves, curves, and rocks, and it stays flexible from -40° to 175°F, so it won't crack in a hard freeze or under summer sun.
The 45 mil thickness is weather and UV resistant and will not crack with age, while still being easy to handle and fold into tight corners. It's safe for fish and plants, ideal for koi ponds, water gardens, streams, and waterfalls.

What size roll do I need?
A common sizing rule is pond length (or width) + 2 × maximum depth + 2 ft for edge overlap. For example, a 30' x 50' roll fits a pond about 25' x 45' that is 18 in. deep. Our pond liner size calculator does the math for you, or call 888-825-6214 and we'll help you size it.
Should I choose 45 mil or 60 mil?
45 mil is the right thickness for most backyard ponds, koi ponds, streams, and waterfalls. For large, deep, or commercial ponds, or rocky sites, consider DuraLiner 60 mil rolls for extra puncture resistance.
How does a roll ship?
Full rolls are heavy and ship by freight. Shipping is calculated at checkout. Call 888-825-6214 with any delivery questions.
Do I need underlayment?
It's strongly recommended. Underlayment protects the liner from rocks, roots, and other sharp objects, and can also be laid on top of the liner before adding gravel and stone.
What's the warranty?
DuraLiner™ EPDM carries a 20-year limited warranty.
