- Protect Pond Liner From Rocks
- No Seaming Necessary
- Use Under Pond Liner
Underlayment is a soft fabric that allows gas to escape, protects your liner from sharp objects and installs easily. Underlayment should cover all surfaces in which the pond liner will be placed. Underlayment does not need to be seamed, joints may be simply overlapped.
