Install a heavy-duty 20 mil HDPE liner that safeguards your koi pond, fountain, or raised bed against expensive leaks.
- You shield buried cables, sensitive roots, and native soil with a tear-resistant sheet built to survive harsh winter thaw cycles and sharp rocks.
- Pick from 10 x 13 ft up to 20 x 25 ft widths to match irregular basins, multi-tier waterfalls, or bottom-irrigation setups.
- The matte black finish inhibits sunlight-driven algae, filters out soil runoff, and preserves pristine water quality for koi and water gardening.
- Pliable rolls contour smoothly over uneven terrain so you can drape, trim, and fasten the membrane rapidly using basic hand tools.
