The best liner for your pond depends on its size, shape, and intended use. Flexible liners, like EPDM rubber or RPE, are often ideal for ponds with irregular shapes or custom designs because they can adapt to irregular contours and natural designs. EPDM rubber is a time-tested material, popular for its long lifespan, durability, UV resistance, and flexibility, making it suitable for larger ponds or those with fish and aquatic plants. However, EPDM is quite heavy, making it difficult to ship and quite expensive, especially when including the cost of underlayment.
RPE liners are affordable, lightweight, and remarkably flexible and durable, and are widely used in larger ponds where high strength is needed. Ultimately, choosing a liner involves considering budget, pond shape, and durability needs to ensure the best long-term results.
