Our essential pond lining solutions are designed for long-lasting, waterproof performance, ensuring a secure and stable base for your aquatic ecosystem.

    Buying guide

    Getting the size right matters more than most people expect, since even a slightly undersized liner can leave you short at the edges once the pond is filled and the material has settled into shape. Measure the maximum length, width and depth of your pond first, then add extra allowance for any planned edging or overhang, or simply use our pond liner size calculator to work out what you need before you order. Beyond the practical side, laying your own liner is genuinely satisfying work: within a weekend you can turn a bare hole into the base for a thriving fish pond or wildlife feature, with the peace of mind of a long manufacturer warranty behind the material itself.

    Not sure which liner?

    What size do I need?

    Use our pond liner size calculator – a liner that's short on one side can't be fixed once the pond is dug

    HDPE or LDPE?

    HDPE is heavy-duty 300gsm with a 40-year warranty; LDPE is 0.3mm with a 25-year warranty

    Do I need underlay?

    Yes – it stops stones and roots working through the liner, and both the HDPE and LDPE warranties need it

    Which underlay?

    Thick 2–3mm with tear and puncture resistance, or 150gsm non-woven in sizes up to 2 x 15m

    What Are Pond Liners?

    A fish pond liner is a material that stops the water from leaking out from the base of your garden pond.

    They're crucial for quality natural ponds, manufactured garden water features and any outdoor fish habitat!

    Good fish pond liners for sale don't just retain the water but keep debris to a minimum and resist a build-up of sediment, ensuring the water quality remains in good condition.

    Why Should I Buy Pond Liners?

    Pond lining is vital since it will prevent water loss and preserve the condition of your garden soil.

    Without liners for ponds, water features will leak into the ground, incurring ongoing costs to refill the water level in your pond and keep your fish and other aquatic species healthy.

    Liner for ponds can deteriorate, so if you notice your water level falling, it may well be time to upgrade to one of the many types of contemporary garden pond liners stocked at AllPondSolutions!

    What Are the Main Types of Pond Liners?
