Pebble-coated liner for the edges of your pond, and for near-natural watercourse designs. The perfect solution for edging of lined ponds or also for installing a watercourse. he 0.5 mm thick, black PVC liner is treated with a coating of fine pebbles via a special technical process. Ideal for the natural transition from pond to garden. We always recommend using normal pond liner under the stone liner, and fixing the edges with pond liner adhesive.
