## Description

Product Description This is Swell UK's most popular pond liner. It's designed to be laid over suitable underlay to keep your pond from draining. Liners are made from a variety of different materials but this one is fashioned from 0.35mm-thick UV-resistant HDPE which is very supple, making installation quick and stress-free. Swell HDPE Pond Liner Pond liners keep the water in your pond from draining into the surrounding earth. A correctly installed pond liner protects your fish and pond as a whole. Unlike other materials that are sometimes used incorrectly, our pond liners are UV-resistant and retain water longer without breaking down. Questions and Answers Q: Is this pond liner easy to fit? A: Yes, although they have no stretch, UV-resistant HDPE pond liners are very supple, making them easy to install in your water garden. Q: How are pond liners measured? A: Pond liners are measured in length and width. However, when deciding on the size of the pond liner you require, it's important to measure the depth of your pond as well as its length and width to ensure a good seal. We offer a wide range of garden pond liners from a small pond liner, such as 2m x 2m, to a large 30m x 40m liner. Q: Do I need to buy anything else with this liner? A: We recommend always investing in a pond liner repair kit to ensure quick repairs and avoid draining. Don't forget to also use a good quality underlay of similar size beneath your liner to help prevent punctures.

Great value liner many thanks

### ⭐⭐⭐⭐ Good but check on delivery

Works fine and although feels thin it's easy to lay and similar to another liner from a direct company that is 30 years old in another pond. Feels flimsy if you have used butyl before. NOTE. Courier that used to be Greek mythology delivered it in badly torn packaging and it could have been punctured. Package better or use a different Courier.
