Aquascape Heavy-Duty Pond Underlayment

Aquascape Heavy-Duty Pond Underlayment is a non-woven, needle-punched geotextile fabric designed to provide superior protection beneath pond liners. Engineered for durability and flexibility, it acts as a protective barrier between the liner and rough or uneven surfaces, shielding against punctures from rocks, roots, and debris while promoting drainage and soil stability.

Available in a wide range of sizes—from 5' x 10' to 15' x 300' rolls—this underlayment is perfect for everything from small water features to large-scale pond installations. The compact rolls are easy to transport and install, while the larger sizes reduce the need for seams in expansive applications.
