4m x 6m Black Pond Liner, L-Grade 200 GSM

Our L-Grade 200 gsm liner in the 4 m × 6 m (≈ 13 ft 1 in × 19 ft 8 in) size is crafted for rectangular or kidney-shaped ponds, stream entries or water features with extended banks. The black UV-stable face gives a natural water appearance, while the grey underside stays hidden.

At 200 gsm, this liner withstands rough substrates, steps and slopes with ease. Its flexibility allows you to form planting shelves and varying depths without joints. Engineered for UV and chemical resistance, it maintains integrity and appearance season after season. (Underlay sold separately.)
