As technology continues to advance, so does the way Toronto plumbers and contractors complete sewer pipe repairs. In the past, there was generally a major excavation that had to take place in order to get to the damaged or leaking pipe. This process was both time consuming and costly. As a result, there have been new advancements in sewer pipe repair over the years including CIPP lining, pipe bursting, and more.
With a large pipe problem, contractors would start digging leaving plenty of room to get to the pipe and the surrounding areas. The excavation process added on extra time and then there were repairs required to the landscaping, concrete, and anything else that had been destroyed. Now, the current processes, completely eliminate the extra damages.
To start, there is a product called CIPP lining that can be used in pipe repair. CIPP stands for cured in place pipe. Relining using CIPP is a modern technology that reinforces existing pipes without doing large replacements to plumbing that is wearing down. It gives the pipe the added strength that is desired without the additional cost.
To do a CIPP lining, contractors use a PVC that is seamless to reline the piping. The material seals into all the cracks and divots that are in the pipe causing the structural integrity issues. Prior to the CIPP lining installation, there is a hydro-jet cleaning done to ensure there is no dirt or debris found that could cause issues with the seal.
A hot steamed pressure then goes through the pipes that applies the CIPP lining to the plumbing fixtures. In the event the pipes are extremely weak or unstable, this process will not work. There is a chance that during the steps necessary to successfully complete the project more harm can be done to the original pipes.
Another method of sewer pipe repair is called pipe bursting. This is common when there is a requirement to replace the entire existing sewer line. To start, there is a small hole or opening made at both sides of the damaged pipe.
After the openings are made, the contractor will feed a thick and stable cable through one end of the pipe. At one end of the cable there is a bursting tool attached and at the other end you will find a PVC or HDPE pipe section. The bursting head takes the old pipe out while simultaneously replacing it with the new pipe.
Before when trenches would have been dug to lay new piping, plumbing contractors now use a sewer line method called moling. With moling there is a machine used that has pneumatic technology. The equipment is run through the ground where the path of the pipe is going to be. Instead of tearing up landscaping and roads, the pipe can be laid in the hole created by the machine.
Over the years, it is not uncommon to find piping or sewer lines that sprig small leaks or start to pull apart causing gaps. Instead of replacing the entire pipe, pull-in-place lining can be installed. To complete this procedure, there are two small holes that need to be dug, one each side of the pipe that needs to be worked on.
After the openings are made, the new liner is put on a wench and then fed through the holes where it is put into place. Finally, a heat or steam is used to cure the material into place for a lasting effect.
Inversion lining is one more way to seal up a pipe that is in fairly decent condition but may have a few minor issues. The liner is made from felt tube and resin. There is only one hole necessary right where the liner will be placed.
