The high quality pond liner underlay materials we supply are all sourced from leading European manufacturers and are superior non-woven, mechanically bonded, needle-punched, polypropylene geotextiles. Our geotextile underlays offer exceptionally high performance and provide a highly effective protective barrier between substrate and pond liner. We recommend that our Heavy Duty Underlay (250/260gsm) is used beneath all our 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. For the smaller garden pond or where preferential ground conditions are prevailant we also supply a Pond Grade Underlay (150/180gsm).
