2.5m x 10m Black Pond Liner, L-Grade 200 GSM

Our L-Grade 200 gsm pond liner in the generous 2.5 m × 10 m (≈ 8 ft 2 in × 32 ft 10 in) size is perfect for creating elongated water features such as garden streams, rill channels or narrow wildlife ponds. The deep black UV-stable surface creates a natural-looking water backdrop, while the grey underside remains concealed below the waterline.

At 200 gsm, this liner delivers exceptional tear-, puncture- and abrasion-resistance across its full length, making it ideal for installations alongside gravel beds, stepping stones or decorative edging. Its flexibility allows you to form smooth curves or straight runs up to 10 m long without seams, while UV and chemical stability ensure your feature stays leak-free and vibrant season after season.
