Aquascape Pond Underlayment

Even high-quality EPDM liners can be punctured by sharp rocks, tree roots, or shifting soil over time. This underlayment acts as a protective cushion, absorbing pressure and preventing tears that could lead to costly leaks.

While specifically designed to complement EPDM liners, this non-woven geotextile fabric is compatible with most flexible pond liners. Its primary purpose is to provide a stable, puncture-resistant base regardless of the specific liner material you choose.

Yes, the non-woven geotextile construction is designed to allow water to pass through while preventing soil migration. This helps maintain soil stability around the pond perimeter and prevents the buildup of hydrostatic pressure that can sometimes cause liner shifting.

Not at all. The fabric is designed to be easily cut with a standard utility knife or heavy-duty scissors. This flexibility allows you to contour it precisely to the shape of your pond excavation, including corners and shelves.

For maximum protection and stability, we recommend overlapping the edges of the underlayment by at least 6 to 12 inches. This ensures there are no gaps where roots or sharp stones could potentially push through to the liner.
