Sewer Pipe Bursting
Pipe lining is not always a possible option however. For instance, if the damaged pipe has any joints or has collapsed, the pipe liner will not be able to be put into place. If that is the case, sewer pipe bursting can be performed instead.
Pipe bursting is another one of the common trenchless sewer repair techniques that involves pulling a large, cone- shaped bursting head through the damaged pipe. The bursting head fractures the existing pipe so it can be extracted. As this is being done, a new pipe is simultaneously pulled into place.
While pipe bursting requires two holes to be dug at either end of the damaged pipe instead of the one hole needed to conduct pipe lining, it is still a far less invasive form of sewer pipe repair that will leave more property around the pipe intact than traditional methods.
