3m x 10m Fabric Pond Liner Underlay, 50 GSM

Our 50 gsm pond liner underlay in the 3 m × 10 m (≈ 9 ft 10 in × 32 ft 10 in) size is crafted from durable black anti-weed fabric to protect your pond liner from sharp stones, roots and ground abrasion. The lightweight non-woven material provides an effective barrier against weed growth while allowing water to drain freely, ensuring both liner integrity and optimal water circulation.

Designed specifically for pond installations, this underlay cushions the liner, reducing the risk of punctures and extending the life of your pond membrane. Its UV-stable composition resists degradation from sunlight exposure, and the easy-cut sheets conform to any shape or contour for quick, hassle-free installation. Simply lay the underlay smooth-side down before positioning your liner to create a reliable foundation for years of trouble-free performance.
