Aquascape HydroDefence® EPDM Pond Liner 1.15 mm – 3 m × 9 m

Aquascape HydroDefence® EPDM Pond Liner 1.15 mm – 3 m × 9 m is a genuine product from Aquascape’s epdm pond liner range, supplied through the current UK contractor catalogue. It sits within our Aquascape selection of HydroDefence 1.15 mm EPDM pond liner in UK sheet and roll sizes. We list the original Aquascape part number and verified specification so it can be matched accurately with the rest of the system.

Product overview: Aquascape pond liners lead in quality and reliability, making them the ideal choice. Liners are available in multiple sizes.

It is intended for projects involving Garden Pond, Koi Pond, Pondless Waterfall. Rather than choosing it in isolation, consider the water volume or flow, physical space, connection sizes, electrical requirements and maintenance access that apply to the finished installation.

What this Aquascape product is for

Allow liner for the full pond profile, shelves, maximum depth and generous edge overlap. The ground should be compacted and protected with suitable underlay before the EPDM is positioned without stretching.

Our practical approach is to work backwards from the finished feature. Confirm what the component must do, where it will sit, how it connects and how it can be reached later. That produces a tidier installation and greatly reduces the risk of ordering a part that is physically similar but technically unsuitable.

Key features and benefits

• Retains water in ponds, Pondless® Waterfalls, and other water features

Compatibility and installation advice

Check the Aquascape part number before ordering, particularly for replacement parts, fittings and products that have changed across generations. For pumps and plumbing, confirm the real operating flow and connection bore. For electrical equipment, confirm the UK power supply, transformer capacity and installation environment. For structural products, allow for ground preparation, finished water level and safe access.

Our practical advice: send us the product numbers of the Aquascape components you already own, or a sketch of the proposed pond or water feature. We can help check the combination before you commit to excavation, pipework or electrical work.
