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

This Aquascape Heavy-Duty Pond Underlayment Roll provides significantly more defense than our Standard Underlayment, being roughly 30% thicker. This extra thickness offers excellent protection against sharp rocks, aggressive roots, and uneven soil that could damage your pond liner. Despite its increased thickness, this Heavy-Duty Underlayment is easy to manage and unroll. Its non-slip surface ensures it stays put during setup, making the process fast and simple. Constructed from soft polypropylene geotextile, it allows trapped gases to escape properly from beneath the liner.
