When selecting a pond liner there’s 4 main choices. PVC, HDPE, EPDM and Rigid liners. All should be fish safe and UV stabilised. PVC (Polymerizing-Vinyl-Chloride) and HDPE ( High-Density polyethylene) are by far the cheapest. While EPDM (Ethylene-Propylene-Diene-Monomer) is easily the toughest and best pond liner available. Rigid liners are strong and durable, but are limited in size. PVC and HDPE are cheaper and have a few limitations. This video talks about these choices so you can determine which pond liner is right for you. ⚠️ Disclaimer: This video is for general educational purposes only.
