Pond Liner, HDPE Pond Liner - AffinityFurn 20 Mil UV Resistant Easy Cutting, for Outdoor Ponds/Waterfall/Fish/Koi Ponds/Water Garden (Black)

1.20 Mil Thick HDPE Construction: Durable & Weather-Resistant for Long-Term Outdoor UseCrafted from high-density polyethylene (HDPE) with a 20 Mil thickness, this pond liner is built to withstand the harshest outdoor conditions. The thick, robust material resists tearing, puncturing, and warping¡ªeven when exposed to heavy rain, strong winds, or daily water pressure. Its UV-resistant design prevents fading, cracking, or degradation from prolonged sunlight (critical for outdoor ponds that stay in direct sun year-round), ensuring it maintains its integrity for years. As a 100% waterproof barrier, it locks in water without seepage, creating a stable, consistent environment for pond plants (like lilies or lotus) and aquatic life (fish, koi, or tadpoles) to thrive. 2.Soil & Water Protection: Low-Maintenance Cleanliness for Healthy PondsThis liner acts as a protective shield between your pond and the surrounding soil, solving two common pond problems: soil accumulation and water contamination. Its smooth, impermeable surface prevents loose soil from seeping into the pond and settling at the bottom¡ªreducing the need for frequent dredging or vacuuming. It also blocks harmful substances (like pesticides, fertilizers, or heavy metals) in the soil from leaching into the pond water, which is vital for keeping fish and koi healthy (no toxic buildup to harm delicate aquatic life). Cleaning becomes far easier, too: simply skim surface debris or wipe the liner¡¯s smooth surface¡ªno stuck-on soil or gunk to scrub away. 3.Flexible & Easy to Use: Adapts to Any Pond Shape & SizeDesigned for hassle-free installation, the liner comes in multiple sizes to fit small backyard ponds, medium koi habitats, or large water gardens. Its soft, pliable HDPE material bends and conforms to irregular shapes¡ªwhether your pond is round, oval, rectangular, or custom-designed with curves or shelves. There¡¯s no need for complex cutting tools (though it¡¯s easy to trim to size with standard scissors or a utility knife if needed): just unroll the liner, place it in your pre-dug pond, and smooth out wrinkles. The smooth surface not only simplifies cleaning but also prevents sharp edges that could harm fish or snag pond accessories (like filters or air stones). 4.Versatile for All Outdoor Water Features: Beyond Basic PondsThis liner isn¡¯t limited to standard fish ponds¡ªit¡¯s a multi-purpose solution for all your outdoor water projects. Use it to line koi ponds (providing a safe, non-toxic space for these sensitive fish), small garden fountains (preventing water loss and protecting the fountain base), backyard waterfalls (ensuring water flows smoothly without seeping into the ground), or decorative water gardens (supporting aquatic plants and small wildlife). It works for both above-ground and in-ground setups, making it a go-to choice for beginner gardeners and experienced pond enthusiasts alike¡ªno matter the scale of your water feature. 5.Key Installation Tips: Ensure Optimal Performance & LongevityTo get the most out of your liner, follow these simple prep steps (critical for avoiding damage and extending its life): First, thoroughly clean your pond¡¯s interior¡ªremove rocks, roots, sticks, or any sharp debris that could puncture the liner. Next, add a layer of round pebbles (or a pond underlayment, if preferred) at the bottom and along the sides. This layer relieves pressure from the water above, cushions the liner against hidden sharp objects, and prevents friction from the soil that could cause wear over time. Taking these small steps ensures the liner stays intact, maintains its waterproof seal, and serves your pond for years to come.
