20-mil Thick High-quality HDPE Pond Liner: Heavy-duty, lightweight HDPE film delivers stronger puncture resistance than many EPDM rubber liners for reliable backyard pond waterproofing.
UV & Weather Resistant for Outdoor Use: UV-stabilized material stays flexible through sun, heat, and seasonal temperature changes—built to help prevent cracking, leaks, and premature aging.
Fish & Plant Safe (Virgin HDPE): Made from virgin HDPE with no harmful chemical additives; water- and acid-resistant so it won’t dissolve or leach into your koi pond or water garden.
Easy DIY Installation & Custom Fit: Soft, flexible liner folds to match ponds of any shape; simple to place, unfold, and fill. Trim/cut to size for ponds, waterfalls, fountains, and water features.
Smooth, Low-Maintenance & Multi-Use: Slick surface reduces sludge and soil buildup while helping block underground contaminants; also ideal as a waterproof liner for raised beds, sub-irrigation planters, and self-watering DIY projects.
