Extremely tough and durable yet lighter to handle and move into position when pond building. Applications: Attenuation Tanks Pond, Stream, Lagoon or Canal Lining Landfill Lining Containment Industrial Location Lining Protection Layer Damp Proof Barrier Water Containment Handy Pond Sizing Guide: Always remember to include enough material for overlap when you purchase your liner. We recommend that at least part of the pond is 1m deep so fish have somewhere to go and keep warm over winter. Plus larger, deeper ponds are much easier to maintain than shallow ponds which can quickly become algae infested. We recommend 1m excess each way (ie, this works out at 0.5m for each 'side'). A simple rule of thumb is as follows: Liner Length Required: max excavation length + twice maximum depth + 1m for overlap Liner Width Required: max excavation width + twice maximum depth + 1m for overlap Package Included: 1 x Fish Pond HDPE Membrane Liner Impermeable Waterproof Garden Landscape Reinforced Check out our other items!
