Know before you buy
Yes, this liner is specifically formulated to be non-toxic and fish-safe. It will not leach harmful chemicals into your water, making it an ideal environment for both aquatic life and plants.
A 45 mil thickness is considered the industry standard for professional-grade pond construction. It provides a robust balance of puncture resistance and flexibility, ensuring it is thick enough to withstand root pressure while remaining easy to fold around corners.
While the EPDM material is highly durable, using a geotextile underlayment is highly recommended. It protects the liner from sharp rocks, roots, or debris in the soil that could cause punctures over time.
Because of its size and weight, it is best to install this liner with at least two or three people. The material is highly flexible, so you can easily drape it over your pond shelves and secure the edges with rocks or landscaping staples.
No, this liner is UV-stabilized to prevent cracking or brittleness caused by sun exposure. Even in areas where the edges are exposed to light, the material is engineered to maintain its integrity for years.
The lifetime warranty covers defects in the material and its ability to maintain a watertight seal under normal pond conditions. It is designed to give you long-term peace of mind regarding the structural integrity of your water feature.
