The high quality pond liner underlay materials are all sourced from leading European manufacturers and are superior non-woven, mechanically bonded, needle-punched, polypropylene geotextiles. These geotextile underlays offer exceptionally high performance and provide a highly effective protective barrier between substrate and pond liner. We recommend that this Heavy Duty Underlay (250/260gsm) is used beneath all pond liners, not only to help protect the pond liner from penetration by sharp stones, roots, etc, but also to reduce excessive localised stretching of the liner when ground settlement occurs over time.
