The 21 m x 0.5 m Bank mat is designed for pond edges, providing essential support for plants in areas where substrate cannot hold. It protects the pond liner from UV exposure and prevents unsightly, bare edges. Additionally, it safeguards the liner during winter from damage caused by sharp ice edges as the pond freezes. This mat allows for optimal root support for aquatic plants and can even be seeded for enhanced greenery. It can be adhered to the pond liner for improved stability.
