Pond Grade UnderLay 150g / SQM 2mtrs Wide (Per Runner Meter)

Our Pond Liner Underlay offers exceptionally high performance and provides a highly protective barrier between substrate and liner . We recommend that our heavy duty underlay is used beneath all our liners, not only to help protect liners from penetration by sharp stones , roots, etc, but also to reduce excessive localised stretching of the liner when ground settlement occurs overtime.
