MAPORCH Pond Liner for Outdoor Ponds - Heavy-Duty 20 Mil HDPE, 16.5 x 26.5 ft, UV Resistant

Meet MAPORCH Pond Liner for Outdoor Ponds — a heavy-duty underlayment designed for koi ponds, fountains, and garden water features. Measuring 16.5 by 26.5 feet, this liner is constructed from virgin 20 mil HDPE, delivering enhanced puncture resistance and long-lasting performance in demanding outdoor settings. With UV resistance and a flexible profile, it blends durability with ease of installation, making it a practical choice for DIY pond projects.

Key benefits lie in material science and thoughtful design. The 20 mil HDPE layer provides tear resistance and puncture protection, helping to guard against accidental damage from rocks and debris. The UV-stable formulation stands up to sun-exposed climates, reducing brittleness in hot days. Being a virgin HDPE product, it avoids added chemicals and is water-safe when installed correctly. The liner is flexible, allowing it to contour to irregular pond shapes without requiring specialized tools or heavy equipment. Its versatile profile means it can serve not only ponds, but also fountains, livestock troughs, and other outdoor water features.

Practical use cases include creating a durable koi pond retreat in a backyard, lining a decorative garden water feature, or replacing an aging liner in a small creek or patio pond. The liner’s easy-cut feature makes it possible to tailor the size to your space, and the long-lasting performance reduces the need for frequent maintenance.
