Product description
This bundle features a 5 m × 5 m (approx. 16.5 ft × 16.5 ft) L-Grade 200 gsm pond liner paired with a 50 gsm anti-weed fabric underlay for complete protection and peace of mind. The deep black UV-stable liner creates a striking water backdrop, while the grey underside remains neatly concealed beneath the surface. The underlay cushions against sharp substrates and prevents weed ingress, ensuring a flawless finish.
Constructed from high-strength polyethylene at 200 gsm, this liner delivers exceptional tear, puncture and abrasion resistance across its entire area, yet remains flexible enough to mould around curves, planting shelves and depth variations without seams. With built-in UV and chemical stability, your water feature will stay leak-free and visually vibrant for years to come.
