Pond liner

FTS tanks creates custom-fabricated fish pond liner.

Before you even start work your most crucial decision is the pond liner. Obviously, you can’t have the water draining away, and you want a liner that will last for a very long time so you don’t have to disturb the pond environment. 

Ideally you want the freedom to fit your pond to your topography and landscape design, without having to install a pre-shaped liner. You also want to go as deep as necessary – at least 4 feet for a Koi pond, for example, and often much deeper.

All this indicates a flexible fabric liner for your fish pond. You need material that is:

  • Flexible enough to fold to the contours and corners of your pond bed
  • Light enough to work with easily.
  • Very strong and not prone to stretching.
  • Highly resistant to puncturing.
  • NON-TOXIC to aquatic life and plants.
  • Highly resistant to UV deterioration.
  • Durable enough to last for decades.
