Pondliner.com flexeible pond liners are made from durable 30 mil fish grade PVC. Any PVC liner you purchase from us will contain UV stabilizers that help protect the liner from breaking down from sunlight. However, even with this protection, PVC Fish Pond Liners usually fail within 2-3 years when left exposed to direct sunlight. You can greatly extend the life of your flexible PVC liner by covering the liner above water level.

All PVC pond liner options are custom sized. One dimension (either the length or the width) must be divisible by 6 feet. Please allow an extra 7 days for your PVC liner to be seamed. You can choose either a blue pond liner or black. All pond liners carry a one year warranty.
