The price of pond liners is influenced by several factors, including material type, size, thickness, and quality. Common materials such as PVC, EPDM, and RPE vary in cost, with EPDM typically being the most expensive. PVC and EPDM require underlayment to protect the liner from punctures and wear, which also adds to the cost. In contrast, RPE liners typically don't require underlayment. EPDM is also significantly heaver than the alternatives, making it expensive to ship and requiring more labor and equipment to install.
Within the same liner material, thickness also plays a role. Thicker liners require more raw materials and may require more complex manufacturing processes to produce. On the balance, though, they tend to be more durable and resistant to damage, which often justifies the higher price. Other factors include the supplier, the material's availability, shipping costs, and whether the liner comes with additional features, such as UV protection or warranties. Installation costs should also be considered if you plan to hire a professional, as labor can add significantly to the overall expense.
