Are you interested in the benefits of trenchless sewer repair? Trenchless sewer repair is a method of replacing old sewer pipes without having to dig them up. There are three main methods of trenchless sewer repair, which vary in how involved and expensive the process will be. Here are your options.
1. Pipe Bursting
Pipe bursting removes the old pipe and replaces it with an entirely new pipe. A special tool is threaded through the older pipe to break it up and pull it out. At the same time, a new pipe is pulled after the pipe bursting tool.
Pipe bursting is a little more involved and less affordable than slip lining, however it has the advantage of not reducing the diameter of the pipe. The pipe is replaced completely with a newer and more durable material, which will last for decades to come.
In fact, pipe bursting can replace an existing pipe with an even larger pipe. Professionals advise this method if the current pipe size has flow or other size-related issues.
Pipe bursting usually cannot be done if the pipe itself has collapsed, because the tool needs to have clearance through the pipe. Further, bursting doesn’t work if the existing pipe has multiple turns because the tools can’t navigate through sharp angles.
2. Slip Lining
During the process of slip lining, a technician threads a smaller plastic pipe through the existing pipe. Once the new pipe has been threaded through, it will be secured into place. Slip lining is the easiest method of trenchless sewer repair. In effect, it creates a smaller, brand new pipe within an older, now unused pipe shell.
Slip lining does have some drawbacks. A slip lined pipe is going to be naturally smaller than the preexisting pipe, which can cause flow issues. A pipe can only be slip lined once because of this: slip lining multiple times would lead to a pipe that is too narrow.
Slip lining is an affordable solution and ideal for those who need a fast repair.
3. CIPP Lining
CIPP lining is similar to slip lining, in that a new pipe is threaded through the existing pipe. However, instead of a whole new pipe being threaded through, it’s instead a liner material that is then inflated to coat the interior of the old pipe.
CIPP liners create an epoxy-like coating on the interior of the older pipe, which creates a solid seal. Despite just being an interior coating, CIPP lined pipes can sometimes last just as long as brand new pipes.
Like slip lining, CIPP lining reduces the diameter of the pipe, which means there may be flow issues if the pipe becomes too narrow. However, it doesn’t reduce the diameter a much as slip lining, and it conveys many of the advantages of slip lining: it doesn’t disrupt the environment, it can be performed quickly, and it is affordable.
CIPP lining does take longer than slip lining, however, because it has to cure for at least one day. CIPP lining can’t be used with pipes that have a lot of angles or pipes that have collapsed, and it doesn’t alter the actual structure of the pipe. If the pipe has become warped or otherwise shifted, CIPP lining will not help.
If you’re in need of sewer repair, a trenchless repair can replace your existing pipe without the need to dig up the surrounding landscaping and features. Any of the above methods will be able to replace most sewer lines, but different methods may be better for different sewers.
