Underlayment

• Protects liner from punctures and abrasion

• Flexible, lightweight, and easy to shape

• Safe for fish, plants, and wildlife

• Adds long-term stability to your pond foundation

Our 6 oz. pond underlayment comes in a 6-foot-wide roll and is sold by the square foot.

Pond underlayment is available for in-store pickup only. Our team can help you choose the right size and amount for your pond.

For best results, use pond underlayment beneath the entire area of your pond liner to protect it against roots and rocks. Underlayment can also be placed underneath large boulders to prevent them from puncturing the liner.
