4m x 5m EPDM Rubber Pond Liner, 900 GSM

This premium 900 gsm EPDM (Ethylene Propylene Diene Monomer) pond liner in the 4 m × 5 m (≈ 13 ft 1 in × 16 ft 5 in) size combines industry-leading durability with exceptional flexibility, making it ideal for garden ponds, koi pools, wildlife habitats and decorative water features. The thick synthetic rubber sheet easily conforms to complex shapes, curves and slopes without creasing, and its robust construction delivers decades of leak-free performance under UV, ozone and temperature extremes.

Unlike thinner liners, the 900 gsm weight provides outstanding puncture and tear resistance, safeguarding against sharp stones, root movement and minor ground shifts. EPDM’s inert, non-toxic composition ensures complete safety for fish and aquatic plants, while its elasticity remains unaffected by heat, cold or prolonged sunlight exposure. Installation and repair are straightforward—small punctures can be patched in situ, and multi-panel seams bond securely with EPDM seam tape and adhesive.
