How Are Drain Relining Processes Completed?
Drain relining is a job composed of several stages. The first is to locate where the leak is occurring. The clear signs will give you a fairly accurate estimation, but you must pinpoint the exact location. Doing this without digging may seem impossible. Thankfully, modern tech allows us to investigate the drainage system with CCTV cameras.
This step doesn’t only look for the source of the leakage. It also surveys the drain pipe to check the severity and size of the problem. Once this data is available, making a decision as to whether relining is suitable becomes easy. In many cases where the affected areas cover a space of centimetres rather than metres, relining is ideal.
Before fitting the new piping wall, the surface needs to be cleaned with a high-pressure water jet. After all, the gunk and junk that has accumulated could make it difficult for the new lining to take. Frankly, this preparation part of the process is vital for the success.
A new bladder is then inserted to cover the source of the leak. This is then inflated so that it can bond with the clean pipe surface to become a sealant. This creates a new internal wall for the pipe, stopping all leaks and preventing further damage to the previously affected area.
Once the new bladder is in place, cameras will be used to check that the entire leak is covered. Moreover, we’ll test to see that water can flow through the fixed piping without disruption or leakages in other parts of the system.
Upon completion, the drainage system will have been restored to its former glory without the need to dig up the land or replace an entire pipe. Perfect.
