If you are looking for a quality pond liner with guaranteed longevity, how does a 20-year guarantee sound? EPDM pond liner is the best choice for backyard ponds, as it’s safe for fish and is even used to line potable water tanks.


Epalyn pond liner, or EPDM pond liner, is a type of rubber membrane commonly used to line ponds, lakes, streams, water storage tanks, and reservoirs. Due to its use in aquatic environments, it is recommended that EPDM pond liners only be ordered from companies in the aquatic trade - read on to learn more!

What is an EPDM pond liner?

EPDM pond liner, short for ethylene propylene diene monomer, is a popular choice for lining garden ponds, lakes, and man-made streams due to its exceptional water retention properties. This synthetic rubber material shares many characteristics with butyl pond liner, making it an ideal alternative. 

An outstanding reputation

There are multiple reasons why EPDM pond liner is the top choice for backyard ponds:


  • It’s highly flexible, allowing it to conform to the shape and features of any pond. It is suitable for ponds of all sizes and can be ordered as a single sheet or a box-welded liner for formal, vertically-sided ponds. 
  • With a greater puncture resistance compared to Butyl, it is extremely durable and can withstand temperature variations from -40°C to 90°C. 
  • EPDM is also resistant to microbial and algae attacks, requiring little maintenance once installed. 
  • It is non-toxic and will not leach harmful chemicals into the water, making it safe for fish, wildlife, and aquatic plants. 
  • It has superior weathering resistance and will not crack or become brittle over time. 
  • It comes with a 12-year guarantee!
