This 1.14mm EPDM rubber liner helps keep pond and lake water safely contained, using a flexible, puncture-resistant carbon black membrane built for outdoor use. It suits garden ponds, wildlife ponds, koi ponds and larger lakes or reservoirs, and stays safe for fish, plants and other aquatic life once installed. Sold by length in feet with a choice of widths, and available with optional AquaSHIELD protective matting underneath.
Key benefits
Here's what stands out about this liner:
- Flexible EPDM construction that's easy to shape around shelves, ledges and irregular excavation profiles
- Excellent puncture and tear resistance, making it a practical choice for large ponds, lakes, lagoons and reservoirs
- Stated UV and frost resistance, intended to help it cope with UK seasonal temperature swings
- Safe for fish, plants and other aquatic life once correctly installed, suiting koi ponds, wildlife ponds and natural swimming ponds
- Can be joined on-site, useful for bespoke shapes or particularly large installations
- Sold by length with a choice of widths, so you can order closer to your pond's actual dimensions
Material and construction
This liner is 1.14mm thick and weighs around 1.39kg per square metre. The manufacturer's figures put elongation (elasticity) at roughly 300%, which allows the membrane to stretch and settle against the ground as the pond fills and the substrate beneath it shifts slightly. That combination of thickness and stretch is part of what gives EPDM its reputation for coping with uneven or settling excavations.
Protective matting (optional)
A protective underlay laid beneath the liner helps guard against damage from stones, roots and other sharp debris in the excavation. This listing gives you the option to add AquaSHIELD matting, available in 200gsm and 275gsm weights, alongside the bare liner.
