Description
Underlayment is the cushion between the soil and your pond liner. It protects the liner from rocks, roots and uneven ground that can puncture it over time. Aquascape Heavy-Duty Pond Underlayment is about 30% thicker than Aquascape's standard underlayment, for rocky, root-filled or uneven sites, and it still spreads easily with a non-slip surface.

Questions
Do I really need underlayment?
Yes, under any flexible liner. One sharp rock or root can puncture a liner months after install, and finding that leak usually means pulling out rock. Underlayment is the cheapest protection in the project.
Heavy-duty or standard?
Choose heavy-duty for rocky, root-filled or uneven soil, or any build with heavy boulders. On smooth, rock-free soil, standard underlayment is usually enough.
How do I install it?
Lay it loosely across the whole excavation before the liner, letting it settle into the shelves rather than pulling it tight. Overlap seams by about 12 inches. Then lay the liner on top.
Can it go on top of the liner too?
Yes. Many builders add a layer over the liner where heavy boulders will sit, for extra protection.
