Need Help Choosing Your Pond Liner?
Choosing the right pond liner is an important step in creating a garden pond that will last. With different materials, thicknesses and liner options available, it can be difficult to know which is best for your project. Whether you're building a wildlife pond, an ornamental garden pond or a larger water feature, our guide will help you compare PVC, Epalyn EPDM and Butyl pond liners, understand their differences and find the right option for your pond.
What type of pond are you building?
Wildlife pond - Designed to attract frogs, newts, insects and birds, with shallow margins and planting areas. Flexibility is useful for creating natural contours.
Ornamental garden pond - A decorative water feature that may include aquatic plants, a fountain or a small waterfall. A flexible liner suits many shapes and sizes.
Koi or fish pond - Requires careful planning around depth, filtration, water quality and fish welfare, alongside a durable, fish-suitable liner.
Raised or formal pond - Built partly or entirely above ground, often with straight sides and defined edges. The liner must suit the structure and be properly supported.
Large pond, lake or reservoir - Larger projects need careful consideration of liner thickness, ground conditions, installation methods and long-term water retention.
Stream or waterfall - Requires a liner that follows the channel contours and is installed carefully to manage water flow and prevent leakage.
Which Pond Liner Material Should You Choose: PVC, Epalyn EPDM or Butyl?
Choosing the right pond liner material will help you build a pond that suits your garden, budget and long-term plans. PVC, Epalyn EPDM and Butyl are all flexible pond liner options, but they differ in their material properties, cost and suitability for different projects.
Here is a simple guide to help you decide which pond liner may be right for you.
PVC Pond Liner – A Cost-Effective Option
PVC pond liner is worth considering if you are building a smaller garden pond and want an economical lining solution. It is flexible and relatively lightweight, making it convenient to handle during installation.
PVC is generally less durable over the long term than premium rubber liners and can become brittle as it ages, particularly with prolonged exposure to sunlight and weathering. For this reason, it is important to consider your pond's intended lifespan and installation conditions when choosing PVC.
PVC pond liner is suitable for many straightforward garden pond designs, but can't be fabricated into a box-welded liner. If you are planning a formal, raised or rectangular pond that requires welded corners, consider Epalyn EPDM or Butyl instead.
Consider PVC if: You are planning a smaller, straightforward garden pond and cost is an important consideration.
Epalyn EPDM Pond Liner – Flexible and Weather Resistant
Epalyn is a synthetic rubber pond liner made from EPDM (ethylene propylene diene monomer). It is valued for its flexibility and excellent resistance to ultraviolet (UV) radiation and weathering, making it suitable for many permanent outdoor pond installations.
Epalyn is available in different thicknesses to suit a range of projects. The 0.75mm option is suitable for many garden ponds, while thicker options provide additional material for installations where greater robustness is preferred.
Epalyn can also be supplied as a flexible sheet or fabricated into a tailor-made or box-welded liner, depending on your pond's design.
Consider Epalyn EPDM if: You want a flexible rubber liner with excellent weather resistance and a choice of thicknesses.

Butyl Pond Liner – An Established Rubber Liner Choice
Butyl rubber pond liner has a long history of use in pond construction. It is valued for its flexibility, durability and suitability for a wide range of pond designs, from ornamental garden ponds to larger installations.
Its flexibility helps it follow the contours of a prepared pond, including curves and planting shelves. Butyl can also be fabricated into tailor-made and box-welded liners for projects requiring specific dimensions.
Butyl is often more expensive than Epalyn, so comparing the available specifications and prices can help you decide which material best suits your requirements.
Consider Butyl if: You want an established rubber pond liner material for a long-term pond project.

Which Pond Liner Is Best for Your Project?
There is no single liner that is best for every pond. Your choice should take into account the pond's dimensions, design, ground conditions, budget and expected service life.
For a smaller, cost-conscious project: Compare the available PVC options.
For a flexible rubber liner with excellent weather resistance: Consider Epalyn EPDM.
For an established rubber liner option: Compare the specifications and price of Butyl.
For a larger or more demanding installation: Consider the appropriate liner thickness and whether a tailor-made or box-welded liner would be beneficial.
Whichever material you choose, careful ground preparation and a suitable geotextile protective underlay
can help reduce the risk of damage during installation.
If you are unsure which material or thickness is right for your pond, contact our team for advice before ordering.
Please note: If ordering our PVC pond liner, we supply to a maximum width of 10m and a maximum length of 25m. PVC is supplied on a 10m wide role hence not being able to cut PVC wider than 10m.
