A flexible 1mm EPDM rubber pond liner, black in colour and made by SealEco. It protects against punctures and leaks while flexing easily around shelves, waterfalls and awkward pond shapes. Suitable for garden ponds, larger ponds and box-welded formal liners, and safe for fish and plants. Choose your width, length and an optional AquaSHIELD protective underlay.
Key benefits
- Flexes easily around shelves, waterfalls and irregular pond profiles, reducing creasing compared with stiffer liner materials
- Good puncture resistance, backed by an elongation of around 300% so the material can move with the ground beneath it
- Rated by the manufacturer to withstand temperatures from -40 to +150 degrees without cracking or splitting
- Unaffected by UV exposure, submersion or microbial attack over long-term outdoor use
- Safe for fish, other aquatic life and plants
- Can be joined on-site for larger or more complex designs
Material and construction
SealEco GreenSeal is 100% synthetic EPDM rubber, 1mm thick and weighing roughly 1kg per square metre. It's produced in Sweden to ISO14000 and ISO9001 standards.
Protective matting (optional)
The liner has good puncture resistance on its own, but stones and roots in the ground beneath it are still a risk. AquaSHIELD protective matting is offered alongside this liner in 200gsm and 275gsm weights, and most pond keepers choose to lay one beneath the liner rather than risk a future puncture.
What's included and aftercare
Your order is cut to the width and length you select, with or without matting depending on which option you choose. Sections can be joined on-site using Elevate QuickSeam Tape and QuickSeam FormFlash, since both Elevate and SealEco use EPDM rubber. If the liner is ever punctured after installation, a pond liner repair kit (sold separately) contains what's needed to patch small holes.
