TROPOW Pond Liner, HDPE Pond Liner - UV Resistant Easy Cutting, Safe for Koi/Fish/Plants, for Fountain/Waterfall/Water Garden (Black)

1.20 Mil LLDPE Material: Durable & Aquatic-SafeCrafted from high-grade Linear Low-Density Polyethylene (LLDPE), this 20-mil thick pond liner strikes the perfect balance between strength and flexibility. The 20-mil thickness (about 0.5mm) delivers exceptional puncture resistance¡ªprotecting against sharp rocks, roots, or debris in your pond¡¯s base that could tear thinner liners. Crucially, it contains no harmful plasticizers or toxic additives, so it won¡¯t leach chemicals into pond water. This makes it 100% safe for koi, goldfish, and aquatic plants, ensuring your water garden¡¯s ecosystem stays healthy. Unlike cheap PVC liners that degrade quickly, LLDPE¡¯s inherent durability means this liner will withstand years of outdoor use without cracking or breaking. 2.Easy Cutting & Flexible Installation for Any Pond ShapeDesigned with DIY pond owners in mind, this liner is lightweight yet rigid enough to hold its shape¡ªmaking cutting and customization a breeze. It requires no specialized tools: just use standard scissors or a utility knife to trim it to fit your pond¡¯s exact dimensions, whether you¡¯re creating a small circular water garden, a long rectangular koi pond, or an irregularly shaped waterfall feature. Its flexible material bends smoothly around corners, curves, and shelves, conforming to uneven terrain without wrinkling (wrinkles can trap debris and harm fish). Even for first-time installers, setup is straightforward: unroll, cut, and lay¡ªno complicated seams or adhesives needed. 3.Versatile for More Than Just PondsWhile optimized for water gardens, this 20x20 ft liner¡¯s versatility extends to dozens of outdoor and utility uses. Beyond ponds, it works as a waterproof underlayment for fountains (preventing water seepage into concrete bases), waterfalls (ensuring consistent water flow without leakage), and even small decorative reservoirs. It¡¯s also useful for non-aquatic projects: use it as a protective covering for outdoor furniture during rain, a waterproof barrier for planter boxes to prevent soil erosion, or an agricultural liner for small irrigation ditches. This multi-purpose design makes it a cost-effective investment¡ªone liner can solve multiple waterproofing needs around your home. 4.UV-Resistant for Long-Term Outdoor DurabilityEngineered to withstand harsh sunlight, this liner features built-in UV resistance that shields it from the sun¡¯s damaging rays. Unlike unprotected liners that fade, become brittle, or crack after months of direct sunlight, this one maintains its structural integrity and black color year-round. Whether your pond is in a fully sunlit backyard or a partially shaded garden, the UV barrier prevents degradation¡ªextending the liner¡¯s lifespan to 5+ years with proper care. This durability means you won¡¯t have to replace the liner annually, saving time and money on maintenance. 5.Protects Water Purity for Healthy Aquatic LifeBeyond holding water, this liner acts as a critical barrier between your pond and the surrounding soil. It blocks harmful substances in the ground¡ªlike pesticides, fertilizers, or heavy metals¡ªfrom seeping into pond water, which is vital for sensitive koi and aquatic plants (these toxins can cause illness or stunted growth). The smooth, impermeable surface also reduces soil accumulation at the pond¡¯s bottom, making it easier to clean and maintain clear water. By keeping water free of contaminants and debris, the liner supports a balanced ecosystem where fish thrive and plants grow lush¡ªturning your backyard into a vibrant, healthy water garden.
