Aquascape Pond Liner & Underlay
Aquascape HydroDefence EPDM liner and protective geotextiles
Shop Aquascape HydroDefence 1.15 mm EPDM pond liner, protective underlay, heavy-duty rock pad and the tapes, patches and accessories used to form and repair durable pond and water-feature membranes. Correct sizing and ground preparation matter as much as the material itself.
What this Aquascape section covers
EPDM provides the waterproof layer; underlay protects it from the prepared sub-base; additional rock pad or geotextile protects high-load areas beneath boulders and structural features. Seam products and patches must be installed on correctly cleaned and prepared membrane in suitable conditions.
How we would plan it
Measure maximum length, width and depth, then allow for both sides, shelves, irregular contours and a generous perimeter overlap. Remove sharp objects, compact the excavation and use suitable protective layers. Avoid cutting away excess liner until the pond is filled and the membrane has settled into its final position.
Need a compatibility check? Send us the dimensions, a simple sketch and any Aquascape part numbers you already have. We will help check the system as a whole before you order.

Why buy Aquascape from That Pond Guy?
We are an independent UK pond specialist, not a general catalogue reseller. Aquascape products are supplied to us through Landscape Plus, and our listings retain the original manufacturer part number so that systems and service parts can be checked properly. If a combination looks wrong, we would rather query it before dispatch than leave you to discover the problem during installation.

Why is the Aquascape part number important?
Closely related products and replacement parts can look almost identical. The manufacturer part number is the most reliable way to distinguish sizes, generations and compatible service components.
Can That Pond Guy check compatibility before I order?
Yes. Send us the existing part numbers, photographs, dimensions and a simple sketch of the proposed system. We can help identify obvious mismatches and the practical measurements still needed.
Should I follow the individual installation manual?
Yes. This category guide explains the planning principles, but the current manual for the exact product remains the authority for electrical safety, excavation, connections, sealing, commissioning and maintenance.
Are rocks, pipework, transformers or other connected components always included?
No. Inclusion varies by product and by kit. Read the individual “What is included” section and check the connected categories before assuming another component is supplied.
How should I plan future maintenance?
Keep pumps, filters, valves, baskets, cartridges, transformers and access covers reachable after landscaping. A small amount of service space designed in now can prevent major disruption later.
