Unbranded HDRPE Pond Liners and Kits | sku-18493551071

This Unbranded 20X25 HDRPE pond liner is listed under Pond Liners and Kits as sku-18493551071, UPC 767629243514. Made in the USA from high-density reinforced polyethylene, it has a 40-mil industrial thickness, built-in UV protection and a smooth surface that limits sediment buildup and makes cleaning easier. It is lightweight, flexible, puncture and tear resistant, and designed to conform to a pond's shape with fewer wrinkles through thermal memory. The liner is described as odor-free and safe for fish, plants and aquatic wildlife, with independent laboratory testing under US environmental standards. Correct installation on a level base, with optional geotextile, is stated to allow up to 40 years of service life. Uses include koi ponds, fish farms, aquaponics and hydroponics tanks, waterfalls, fountains and rainwater tanks. The material can also patch existing liners or leaks; cover roofs temporarily; protect work surfaces, truck beds or stored items; and serve as a drip cloth, ground cover, splash guard or sacrificial layer. It can be shaped into temporary pools, foot-soak pools, trays, containers, diversion channels and wet zones for habitat or theatrical effects. Other suggested uses are liners for planters, French drains, kennels, sandboxes, well pits, green roofs, compost areas and sub-irrigated grow beds, plus weed barriers, craft projects and boundaries between sand and gravel. Scraps can be used for smaller sealing or protection jobs. Check material safety before using it for animal habitats, and use an acid-resistant liner where compost leachate will be collected. To size a liner, add pond length or width to 2 times the depth and another 2 feet. For example, a pond 10 feet long, 6 feet wide and 2.5 feet deep calls for a 17 x 13 foot liner. For a rectangular or square pond, multiply length, width and depth by 7.5 to estimate gallons. For a round pond, multiply radius by radius, then by 3.14 and 7.485. Installation is intended to be manageable without heavy machinery.
