Product description
Premium 900 gsm EPDM pond liner in a 3 m × 3 m (approx. 9.8 ft × 9.8 ft) cut size combines industry-leading durability with exceptional flexibility, making it perfect for garden ponds, koi pools, wildlife habitats and decorative water features. The thick synthetic rubber sheet moulds effortlessly around intricate shapes, curves and slopes without creasing, while its inert, non-toxic composition guarantees safety for fish and aquatic plants. Underlay is necessary to protect against sharp stones, root intrusion and ground shifts (sold separately).
At 900 gsm, this liner delivers outstanding puncture and tear resistance, safeguarding against abrasive gravel, root movement and temperature extremes. Engineered to resist UV, ozone and chemical exposure, it remains pliable from freezing winters to scorching summers, promising decades of leak-free performance. Small punctures can be patched in situ and multi-panel seams bond securely with EPDM seam tape and adhesive for simple upkeep.
