Key benefits Reliable waterproof barrier: 8 mil (0.12 mm) HDPE liner forms an effective waterproof, antileakage layer to protect water and pond equipment. Durable and punctureresistant: tensile and impact strength resists tears and punctures for longlasting performance in common pond conditions. Easy to shape and install: Flexible material bends and folds to fit irregular contours and can be cut to the exact shape you need. Lowmaintenance, cleaner water: Provides a smooth, flat surface that reduces soil accumulation and prevents harmful substances in the soil from leaching into the pond. Features and performance Material: 8 mil (0.12 mm) density polyethylene (HDPE) with tensile and impact strength. Function: Waterproof, antileakage barrier that resists tears and punctures. Compatibility: Flexible design fits almost any pond shape and can be trimmed to size for custom installations. Maintenance: Smooth surface makes cleaning easier and reduces sediment buildup and soilborne contaminants. Practical use scenarios Koi and ornamental fish ponds: Creates a reliable, nonporous liner that protects water quality and reduces the risk of leaks threatening fish environments. Backyard water features and garden ponds: Easily cut and fit around rocks, steps, and planters to form complex shapes while maintaining a consistent waterproof barrier. Pond and retrofit: Use as a replacement or reinforcement layer when repairing existing ponds or upgrading liners to improve leak resistance and reduce maintenance. Installation and care tips Trim to fit: Lay the liner with some overlap at edges, cut to shape, and secure per your pond edging method. Protect from sharp objects: Although punctureresistant, avoid placing sharp rocks or tools directly against the liner during installation. Cleaning: Routine removal of debris and occasional gentle rinsing will keep the flat surface clear and help maintain water quality.
