The right ingredients for every pond size: organic pre-formed ponds with integrated planting zones and architecturally shaped pre-formed ponds in angular forms are designed for smaller garden ponds. For larger, freely designed garden ponds, swimming ponds and koi ponds, the substrate is first protected with fleece and then covered with pond liner. The rule of thumb for choosing the liner is: the larger the pond, the thicker the liner should be. You can also obtain installation materials from us, such as liner adhesive or universal adhesive for joining the liners. We also stock a wide range of hoses, distributors, pipes, connectors and water reservoirs.
