Keep Your Fish Secure: By using a pond liner, you can prevent water and soil from seeping out of the pond and contaminating water resources. This will create a better living environment for your fish. Moreover, you can add aquatic plants, rocks, and wildlife to make your pond more attractive.
✓
45 Mil Super Thick: The pond liner is 30' x 35' in size and is designed to be puncture and tear-proof. This means that you don't have to worry about sharp rocks or root growth damaging the liner. Additionally, the liner provides a flat surface and reduces soil buildup, which makes cleaning your pond easier and quicker.
✓
Prevents Aging: Our fish pond liner is made of premium EPDM material. This means that even when exposed to direct sunlight, the liner will not crack, split or deteriorate, allowing it to retain its properties for years to come.
✓
Flexible & Pliable: Our pond lining is flexible and easy to bend and fold, making it suitable for almost any pond shape. Before purchasing, it's important to determine your pond's precise depth and width. We recommend buying a liner that's slightly larger than your pond. Any excess liner can be easily cut off after installation.
✓
Natural Pond Look: No tools required for installation. It's suitable for a variety of water features, including water gardens, waterfalls, outdoor ponds, fish/koi ponds, and more. The liner can even be extended for use in planting beds and other self-watering projects.

👉[Durable & Leakproof]: The KOI pond liner is with unique five-layer structure design. The middle is reinforced HDPE with net structure PE and leafproof coating on both sides. It’s more durable and leakproof than most pond liners in the current market.
✓
👉[Easier to Work With]: Thanks to its unique structure, the fish pond liner is softer and more flexible. It's easier to fold and cut to any sizes, so as to fit for nearly any shape ponds outdoor. We understand how hard it is to work with when the pond liner is too stiff.
✓
👉[Excellent Performances]: Because of its five-layer structure, the pond liner is with relatively high puncture & scratch resistance. Suitable for high & low temperature environments outdoors. We have tested repeatedly that the pond liner can be used for over five years.
✓
👉[Widely Used Applications]: Our reinforced PE pond liner was originally mainly used for large-scale aquaculture and waterproofing projects. Now we could use the it for duck & fish/KOI ponds, man-made waterfalls & fountain, raised planter bed or pool ect. Your ponds need a lasting liner.
✓
👉[Warm Tips]: Please level ground and place underlayment before laying the pond liner, such as sand, old carpet and any others sheet of fabrics. Avoid hard and sharp objects to pierce pond liner. Please freely reach out to us if you have any questions, we will work it out until your satisfaction.
