Aquascape Pond Underlay & Geotextiles
Protect pond liner with Aquascape underlay and geotextiles
Compare Aquascape pond underlay, heavy-duty rock pad, gravel barrier grid and geotextile products used beneath and above liner. These layers protect the waterproof membrane, stabilise selected areas and provide additional resistance beneath rocks, boulders and structural modules.
What this Aquascape section covers
Underlay below the membrane protects against small stones and irregularities in the prepared ground. Rock pad or additional geotextile above the liner spreads local loads and reduces abrasion beneath heavy decorative stone. Gravel barrier products serve a different retaining or separation role and should not be treated as a substitute for puncture protection.
How we would plan it
Prepare and compact the ground before laying protection. Overlap adjoining underlay without leaving exposed gaps, remove sharp folds and add targeted protection in high-load areas. When moving boulders, use lifting methods that avoid dragging them across the liner.
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.
