Heavy-Duty Pond Underlayment, 15' x 300' Roll

The Aquascape Heavy-Duty Pond Underlayment 15' x 300' Roll is a commercial-volume supply of geotextile pond underlayment for landscape contractors, pond installation companies, and large-scale commercial water feature projects. At 4,500 sq ft (418 sq m), it covers multiple large-scale installations from a single supply source.

Commercial-Volume Supply for Installation Businesses

Buying underlayment by the large roll eliminates per-project material sourcing, reduces per-square-foot cost compared to pre-cut pieces, and ensures material consistency across all installations completed from the roll. Contractors building multiple ponds per season benefit from stocking this size and cutting to project requirements at the job site.

How to Use

Unroll and cut to project dimensions at each installation site. Lay over prepared, cleared substrate. Overlap seams by 6" (15 cm) minimum. Install EPDM liner over the underlayment and fill to seat both layers. Store unused roll sections in a dry, covered environment to prevent degradation before use.

Ideal for professional pond and water feature installation contractors who build multiple projects per season and prefer to manage underlayment supply from a commercial-volume roll.
