Pond liners made from HDPE and polyethylene give you a clean, watertight base for backyard ponds, koi ponds, streams, and water gardens. This HDPE pond liner bends to curves without cracking, so shelves and corners lie flatter and look smoother under stone.
Built for outdoor exposure, the polyethylene pond liner is UV-resistant, puncture-resistant, and designed to handle shifting soil, roots, and seasonal freeze-thaw cycles. Pair it with pond liner underlayment or non-woven geotextile to protect the sheet and extend service life. Measure length, width, and maximum depth, then add overlap for anchoring under coping. When you buy through Zalwan Ltd, you get straightforward sizing support and liner options that fit small ponds and larger landscape installs. If your pond includes a waterfall or stream run, plan extra liner length so you can tuck it under boulders and prevent channel leaks.
For most backyard ponds, thicker options offer better puncture resistance. If your soil is rocky or you expect heavy foot traffic.
Yes, it can be fish-safe with proper installation. Rinse the liner before filling, and avoid harsh chemicals or contaminated gravel.
Strongly recommended. Underlayment helps protect the liner from sharp stones, roots, and compacted soil, which improves durability.
