What Is Trenchless Sewer Replacement?

In traditional sewer replacement, professionals dig a trench in the yard and remove or replace the section of clogged or damaged pipe. Trenchless sewer replacement is very different. With the benefits of trenchless sewer replacement, homeowners are able to repair their sewer without digging up their lawn.  
What Is Trenchless Sewer Replacement?
Trenchless sewer replacement is a type of sewer replacement that involves breaking out or replacing an old sewer pipe without digging a hole. Two different types of trenchless sewer replacement exist: pipe lining and pipe bursting.
The type of sewer replacement that is best for a property depends on the type of damage that the old sewer sustained. Usually plumbers will decide which type to use based on a camera inspection that reveals the type of damage sustained by the old pipe.
Pipe Lining
In the pipe lining method, professionals dig an access hole to the sewer line, then they pull a deflated flexible pipe lined with resin through the old pipe in the ground. Once in place, the new pipe is inflated. Eventually the resin hardens to hold the new pipe in place. The new pipe is more narrow than the old pipe, but not by much. T
his method works well if the old pipe still has structural integrity. In cases when the old pipe has been crushed, pipe lining does not work.
Pipe Bursting
The pipe bursting method involves digging two access holes at either end of the sewer line. The plumbers then break the old pipe open by a bursting head. At the same time, they drag a new pipe into the hole behind the bursting head. Pipe bursting is the best option for pipes that are so seriously damaged that pipe lining is an impossibility.  
What Are the Advantages of Trenchless Sewer Replacement?
The greatest advantage of trenchless sewer replacement is that it involves no digging. Traditional sewer replacement can be very disruptive because sewer lines often run beneath parts of the yard that are expensive to replace.
Traditional sewer replacement may involve breaking up sidewalks, driveways, garden beds, pathways, lawn sculptures, and more. Trenchless sewer replacement involves digging only one or two holes in the yard, depending on the type of sewer replacement taking place. This saves homeowners hassle and as well as money on landscape repair.
What Are the Disadvantages of Trenchless Sewer Replacement?
Trenchless sewer replacement may not involve a trench, but it does involve a hole or two, depending on the type of sewer replacement being conducted. This typically involves minimal yard repair, but it can still sometimes be very invasive.
In addition, the trenchless sewer replacement process can be more expensive than traditional sewer replacement. However, many homeowners find that the cost savings from not replacing the landscape often makes trenchless sewer replacement less expensive than the alternative overall.
