Protective Pond Underlayment is recommended to add a protective ground barrier for the pond liner. After digging, especially if you encounter rocks, roots, or other objects, this light weight durable underlayment will protect the liner from settling damage. This underlayment is placed directly on the excavation prior to placing the liner.
|Select the amount of underlayment needed to cover the ground excavation. The liner will then set on top. You may need to section pieces to best cover the excavation.|
