Service life and resilience of pond liners
How many years your pond seal remains effective is largely determined by two factors: the material you choose and the care taken during installation.

A smooth substrate, cleared of stones and debris, is the best way to increase its durability significantly. As a general rule, you can expect a PVC pond liner to last between 10 and 20 years, whereas a high-quality EPDM pond liner can often last over 30 years.

Decision guide: PVC or EPDM pond liner?
To find the ideal liner for your project, consider the size of the pond, the nature of the ground, and your long-term goals.

  • For standard projects: PVC pond liners have established themselves as a proven solution for small to medium-sized garden ponds with straightforward layouts.
  • For the highest requirements: If you are planning a large-scale Koi pond or a particularly long-lasting installation, EPDM is the premier choice. This type of liner is extremely elastic and is primarily recommended when maximum UV resistance and flexibility are required.
