Types of Koi Pond Liners

  1. EPDM Rubber Liners: EPDM (ethylene propylene diene monomer) is a type of synthetic rubber that is commonly used as a koi pond liner. It is flexible, durable, and resistant to UV rays and weathering. It is also safe for fish and plants, making it an ideal choice for koi ponds.
  2. PVC Liners: PVC (polyvinyl chloride) liners are another popular option for koi ponds. They are flexible, easy to install, and come in a variety of thicknesses. PVC liners are resistant to UV rays and weathering, but they can become brittle over time, which may lead to cracking and leaking.
  3. Rigid Plastic Liners: Rigid plastic liners, such as those made of HDPE (high-density polyethylene), are a more permanent solution for koi ponds. They are durable, resistant to UV rays and weathering, and have a long lifespan. However, they are more difficult to install and may require professional installation.

Factors to Consider When Choosing a Koi Pond Liner

  1. Size of Pond: The size of your pond will determine the type and thickness of the liner you need. For larger ponds, a more durable and thicker liner is required to withstand the weight of the water and the fish.
  2. Depth of Pond: The depth of your pond will also impact the type of liner you need. Deeper ponds require thicker liners to withstand the pressure of the water and prevent leaks.
  3. Type of Fish: The type and size of fish in your pond will also impact the type of liner you need. Koi are larger and heavier than other types of fish, so a more durable and thicker liner is necessary to prevent damage and leaks.
  4. Climate: The climate in your area will also impact the type of liner you need. If you live in an area with extreme temperatures or frequent weather fluctuations, a liner that is resistant to UV rays and weathering is essential.


Choosing the right koi pond liner is essential for the health and longevity of your pond and its inhabitants. EPDM geomembrane rubber, PVC, and rigid plastic liners are all viable options, but each has its own set of advantages and disadvantages. When choosing a liner, consider the size and depth of your pond, the type of fish you have, and the climate in your area. With the right liner, your koi pond can provide years of beauty and enjoyment for you and your family.
