When I think pond liners, I think of the sound of running water uninterrupted by a quiet water pump, as well as garden solar lighting, and a lovely barbecue in my garden with the patio heater keeping me cosy. Making a beautiful pond that reflects the image I’ve portrayed start with a humble pond liner which should be extremely durable and puncture resistant, highly resistant to the sunlight causing damage, and the best pond liners will remain in top condition for many years to come. Based on these characteristics I’ve reviewed the best pond liners to save you time.
