EPDM pond liners come in a variety of thickness, with the most common width being around 0.045 inches, or 1.14 mm. The thinnest EPDM liners are usually around 0,030 inches or 0.76 mm, and the thickest options can range up to 0.090 inches or 2.29 mm thick. Which thickness of EPDM is best for your needs will depend on a variety of factors. This includes the shape of your pond, any aquatic life you intend to keep, and the overall durability and lifespan you require. Thicker liners are typically more durable and resistant to damage, but they can also add to the overall cost and may not be necessary for less demanding applications.
When choosing an EPDM pond liner for your project, it's important to consult with a professional or do your research to determine the appropriate thickness for your specific needs. You should also ensure the liner you choose is compatible with any other materials or products you plan to use in your pond installation.
