This is an alternative to the natural replacement of old pipes. A hose-like balloon is coated with epoxy resin, and is fed into the existing duct with compressed air. This resin hardens in about a day and essentially turns into a new tube inside. The cost is usually half the cost of physically replacing the piping. In 90% of cases, used in the sewer system, but sometimes water pipes are also restored. The warranty from the manufacturer is for 50 years. You can find one of the manufacturers of this method here.
