You might wonder where your sewer lateral is located and how an Ottawa plumber would conduct repairs if the sewer pipe is buried deep underground. Plumbing technicians and engineers wondered about the same thing back in the 1960s and 70s. An agricultural engineer once realized that he had a leaky pipe under his concrete garage floors and wondered how he could potentially fix it without having to dig up the ground and cause an expensive mess.
That engineer’s name was Eric Wood, and he was one of the founding fathers of trenchless technology. He first invented the “cured-in-place pipe,” also known as CIPP and pipelining. During that process, an inflatable felt tube is soaked in epoxy, carefully lowered into the damaged pipe, and placed against the damaged area to seal either a crack or a hole.
Although it was a success, many professional plumbers remained doubtful about this technology until it became more refined by inventing and improving plumbing tools, such as the video inspection camera, hydro jetting, and experimenting with other potential trenchless methods.
Nowadays, we cannot imagine a plumbing world without this useful technology. There are various options for trenchless sewer repair in Ottawa, but we will focus on the two main ones that are practiced regularly:
Pipe Relining
As previously mentioned, CIPP stands for “cured-in-place piping,” during which a replacement liner is inserted into the damaged sewer to cover the affected area. When the epoxy cures, your sewer line will have its original functions restored. However, to make that happen, the relining tube has to be of a smaller diameter than the original sewer line. This doesn’t pose any issues as long as the original lining is in good condition. Sometimes, the damaged section of the original sewer line is irreparable and needs to be replaced. For that, we also have a trenchless sewer line repair option.
Pipe Bursting
During this repair process, we use hydraulic technology to break, lift and push out the severely damaged section. To make that possible, your local Ottawa plumbers drill two small reception holes to access the broken pipe. As they break the old section into pieces and remove its remains with a pulling rod, a new pipe liner is pulled into place. The bursting method is often deemed as a more optimal trenchless repair because it helps restore the sewer line’s original function by keeping the diameter at the same size. That’s one of the main advantages of pipe bursting.
