There are also disadvantages, but they are determined by the properties of materials. The cheapest option for film insulation will be the use of polyethylene film. When installing the pond, you should use a two -layer film with a thickness of 500 mK. But this option will be fragile, since this film is easy to break if there is a mechanical effect or in large frosts, it is not a stand against the effects of ultraviolet rays.
PVC film will be more expensive and more stable, but it has a number of disadvantages that are similar to the shortcomings of the polyethylene film. The advantage of this film is that you can work with it using special tools. Such isolation can last up to ten years. The most expensive and most reliable material for waterproofing is a buttonage. It perfectly opposes the sun’s rays, has strength, plasticity, and also tolerates winter frosts well. Such waterproofing is about the average of about fifty years.
