Product features and benefits Material and performance: Made from HDPE. Our HDPE formulation is more waterproof and leakproof than other HDPE materials, providing reliable water retention for ponds and water features. Thickness: 0.12 mm (5 mil) offers tear and puncture resistance. The liner resists damage from sharp stones and plant roots and tolerates uneven pond bases without compromising water containment. Durability: Designed to withstand tears and punctures that commonly occur during installation or service life, helping protect your investment and reducing the need for frequent repairs. Easy to handle and install: The liner is lightweight, foldable, and easy to cut to size. It stretches around corners and fits irregular shapes, so you can tailor it to almost any pond layout with simple tools. Water and soil protection: Effectively blocks substances in the surrounding soil from entering the pond, helping keep water clean and supporting a healthy environment for fish, plants, and wildlife. Also makes routine cleaning and maintenance simpler. Why this liner solves common problems Prevents leaks from sharp objects, roots, and uneven ground that often puncture lesser liners. Keeps pond water contained and from soil contaminants that can cloud water and harm aquatic life. Simplifies installation and for nonstandard or irregular pond shapes. Typical applications Backyard or garden ponds: Line decorative or planted ponds to protect water quality and prevent leaks around rocks and roots. Fish or koi ponds: Provide a punctureresistant barrier suitable for ponds with gravel, stones, and active fish. Small water features and temporary reservoirs: Use for formal or informal water features, seasonal stock watering, or temporary irrigation basins where a reliable waterproof barrier is needed. Practical notes Cut to fit with utility knife or scissors. Allow extra material for seams and anchoring around edges. Place a protective underlay or sand bed where large sharp stones are present for added puncture protection (recommended but not required). Compatible with irregular pond shapes and standard landscaping installation techniques. This HDPE fish pond liner combines a thin, flexible profile with strong waterproof and punctureresistant performance for easy installation and longlasting pond protection.
