Gordon Low Pond Liner Underlay Sheet - 2x5m

Why do you need to use underlay?

• Protects the pond liner from being punctured by rocks and rough edged stones buried in the ground,
• Forms a barrier to the potential risk of damage by rodents,
• Prevents the liner shifting about due to ground movement,
• Protective underlay liners are made from synthetic materials so do not rot or deteriorate over time.
