When choosing a pond liner, consider your budget and the type of pond you're creating. An underlayment like UnderGuard helps protect the liner from punctures caused by sharp objects in the soil.

Pond liners are watertight materials placed on the bottom and sides of a pond to prevent water from leaking. They keep water levels consistent, prevent soil erosion, and provide a stable environment for plants and fish.

For more information, view our LifeGuard Specifications, LifeGuard MSDS, and Safety Test.
