As technology advances, so does the way contractors and plumbers perform sewer pipe repair. In the past, plumbers need to perform a major excavation to get to the leaking or damaged pipe. This process was both costly and time consuming. However, there are technological advances in repairing sewer pipes.
Contractors would dig when faced with a big pipe problem, which leaves plenty of room in order to get to the pipe. The excavation process require an extra time with the needed repairs to the concrete, landscaping and anything else that had been damaged.
Here are the common varieties of repairing sewer pipe:
1. Cured in place pipe (CIPP) can be used in sewer pipe repair. Relining with the use of CIPP is a modern procedure, which reinforces the existing pipes without performing large replacements. It provides the pipe additional strength, which is desired with no additional cost.
Contractors use seamless PVC to reline the piping to do the CIPP method. The material seals divots and cracks which are in the pipe that causes the structural integrity problems. Contractors will do a hydro-jet cleaning to make sure there is no debris or dirt found that could cause seal issues before the installation of CIPP lining.
2. Pipe bursting is another method of pipe repair. This is a common method when there is a need to replace the whole existing sewer line. You need to make a small opening or hole at both sides of the leaked pipe.
The contractor needs to feed a stable and thick cable on one end of the pipe after making the openings. There is a bursting tool linked at one end and you will find a HDPE or PVC pipe section at the other end of the cable. The bursting head removes the old pipe while replacing it simultaneously with new pipe.
3. Plumbing contractors use a moling sewer line method, while they need to dig trenches to lay new piping. There is a machine applied with pneumatic technology with moling. The machine is being run through the pipe, which can be laid in the hole made by the machine, rather than tearing up roads and landscaping.
Over the years, it is usual to find sewer lines or piping with small leaks or begin to pull apart that causes gaps. Contractors can install pull-in-place lining rather than replacing the whole pipe. Contractors only need to dug two small holes one each side that has to be worked on to finish the procedure. The new liner is placed on a wench and pushed through the holes after making the openings. A steam or heat is used in order to cure the material to have a lasting effect.
4. Another way of sealing up a pipe which is in good condition but might have some minor issues is inversion lining. The liner is created from felt resin or tube. Contractors only need one hole in which the liner will be placed.
These current processes of sewer pipe repair eliminate the extra damages caused by excavation process, which saves you a lot of time and money.
