Building ponds permanently, part 1: Ideal swimming, fish and natural ponds https://www.naturagart.de In this video you will learn everything you need to know about the effects of UV radiation on pond liners and how you can extend the life of your pond. UV radiation can damage the structure of plastic films, which can lead to premature aging and ultimately to the failure of the pond seal. The speaker uses an example from his nursery to demonstrate how a film that is over 15 years old was significantly damaged by UV radiation. It is also explained that sunlight, especially the short-wave UV components, can reach and damage the pond liner even under water, which is a problem especially in plant-free swimming ponds. To solve this problem, the video presents various methods of how to effectively protect the pond liner. One option is to use a special bank mat in combination with a bank tape, which enables permanent and secure bank protection. For the underwater area, a sandwich construction is recommended, in which a thin safety film, a solid protective fleece and the actual pond liner are placed on top of each other. In addition, a thin middle layer of Naturagart pond construction mortar can be applied, which is extremely mechanically resilient and offers effective protection against UV light and damage caused by animals. This process ensures that the pond liner is protected from above and below and that the pond looks natural. Other videos and instructions from Naturagart provide detailed information on how to create such ideal ponds yourself. More videos about pond construction: https://www.naturagart.de/Videos/Teic...
