Selecting the right liner: PVC or EPDM?
Determining the most suitable material depends on your pond's dimensions, soil conditions, and your target service life:

  • PVC pond liners represent the standard solution for small to medium-scale garden or ornamental ponds with straightforward geometries.
  • EPDM pond liners are the premier choice for large-scale installations, koi ponds, and projects prioritising maximum longevity, as they are exceptionally elastic and resilient.

EPDM is particularly recommended if you value high flexibility during installation and permanent UV stability.

What is the expected service life of pond liners?
The durability of a liner is primarily dictated by the material quality and the precision of the installation:

  • PVC pond liners: typically offer a service life of 10 to 20 years.
  • EPDM pond liners: frequently achieve a lifespan of 30 years or more.

By ensuring a smooth substrate cleared of sharp stones and debris, you can significantly extend the liner's operational integrity.
