Rubber membranes have been used for waterproofing on roofs, reservoirs and channels for over 40 years. The history of the material is a guarantee in itself.  In contrast to plastic, a rubber membrane is highly elastic.  It can be elongated up to 300% without changing the properties, giving minimal risk for leakage.

GreenSeal pond liner is available both as standard panels and made to measure to fit the size of your pond. Sizes up to approx. 800 sqm can be supplied as a single panel.

GreenSeal is not harmed by UV-radiation from the sun, constant contact with water, vegetation or micro organisms. The strength and flexibility are unchanged from the warmest to the coldest of climates. GreenSeal is also chemically stable and does not contain any softeners or other chemicals harmful to the environment. You can be confident that fish and other animals as well as plants are unaffected by the membrane.

With GreenSeal you will have a problem-free garden pond for decades.
