Many times we find work where specific points have to be solved in a section of the pipeline, taking into account the cost for the owner of having to cut the pipe (if instead of 30 meters, we only repair the exact point of the problem, which can be after an elbow at 10 meters, for example) although the most convenient would be to repair the entire section, but the insurance companies do not pay for preventive maintenance, so they are happy for the fast. patch liner repair fix.
If the work is financed by the owner and a joint is separated, or because of wear and tear it presents problems in half of your property and is allowing the loss of water in any place, then, in contrast, why realign 30 meters when can we seal the open and leaking joint saving time and money?
In the same way we have observed, if there are several connections or joints in a drainage section, the traditional drainage lining would mean aligning the entire section and then a system would have to be used to open the lateral connections, with patch lining repairs, you can Easily repair joints and defects between connections without digging or robotic cutting, with proper access.
Repairs with patches could be faster and more economical in many cases.
