3m x 4m Black Pond Liner, L-Grade 200 GSM

This L-Grade 200 gsm liner in the 3 m × 4 m (≈ 9 ft 10 in × 13 ft 1 in) size is tailored for medium garden ponds, rill features or decorative water installations. The UV-stable black face enhances water clarity, while the grey underside remains out of sight.

Despite its moderate size, the liner delivers robust puncture and tear resistance around rocks and slopes. Its flexibility lets you form planting ledges and depth variations, while UV and chemical stability ensure long-term, leak-free performance. (Underlay sold separately.)
