SealEco GreenSeal Pond Liner SealEco GreenSeal EPDM is the most flexible liner on the market, and a stalwart of any landscaper or building professional. Seen as the cheaper yet superior alternative to Butyl pond liner, SealEco EPDM is suitable for ponds of all sizes, fabricating into formal, box-welded liners, and even lining water containment tanks. For natural ponds, the EPDM pond liner can be supplied as a single sheet to your required size and then trimmed to the exact shape once installed. Please note: This material comes from SealEco in 1.7m width rolls so any sizes greater than this will have factory joins. This does not affect the quality or the guarantee of the liner. For formal shaped ponds (with vertical sides and a flat base), including Koi ponds, ornamental ponds, water features, and rills, SealEco EPDM can be fabricated and supplied as a box welded liner to your exact requirements, which will sit within the structure without any unsightly folds. These are fabricated in our factory and supplied as a single item. Why choose EPDM Pond Liner? Butyl Pond Liner: SealEco EPDM has a slightly embossed texture and pure black colour similar to Butyl. It is 100% synthetic and has a greater puncture resistance and flexibility compared to butyl whilst also being cheaper. Highly flexible: This means this EPDM pond liner is greatly suited to working around shelves, waterfalls or other features you may wish to add to your pond whilst creasing less, creating a better visual appearance. Very durable: EPDM pond liner is not harmed by UV radiation, contact with water or microbial attack. It can also withstand temperatures of up to -40 to +150, so will not crack or split. Human, fish and animal safe: SealEco EPDM is certified safe for humans, fish and animals, and is also environmentally friendly, having been produced in Sweden to ISO14000 and ISO9001 standards. Onsite joins: As Elevate and SealEco are both EPDM rubber pond liner materials, it is possible to use Elevate QuickSeam Tape and QuickSeam FormFlash to join sections of SealEco for more complicated designs. Aftercare: In unfortunate cases, you may require a pond liner repair kit. Containing everything you need to repair small holes within your liner, it is an immediate solution to repair any damage that may have occurred to the liner.
