5′ Wide X 360′ Long Roll – Pond Liner 4oz Underlayment

The DuraLiner™ 4 oz Underlayment Roll provides a strong, non‑woven geotextile layer designed to protect pond liners from punctures and abrasion. Made from durable 4‑ounce fabric, this underlayment adds a dependable barrier against roots, stones, and other sharp objects that can damage liner material during installation or over time. Its 5‑foot by 360‑foot roll format makes it ideal for large ponds, streams, and water features, offering consistent coverage and enhanced soil stability. The material can also be installed above the liner when adding gravel to prevent wear from shifting stone. Engineered for long‑term performance, DuraLiner™ underlayment helps create a stable, protected foundation for any pond or water garden installation.
