Heavy-Duty Pond Underlayment – 15′ x 300′ Roll

The Aquascape Heavy-Duty Pond Underlayment Roll is approximately 30% thicker than our Standard Underlayment. This increased thickness provides superior protection against rocks, roots, and uneven soil that may damage the liner. Despite its added thickness, the Heavy-Duty Underlayment is easy to install and features a non-slip surface for a hassle-free application. The soft geotextile, crafted from polypropylene, allows for proper gas escape, preventing any buildup beneath the liner.
