If only a short section of a sewer pipe is defective,
the short liner method can be used.

In contrast to the open-cut method, the advantages of short liner methods are numerous. For example, there is no need to break up the soil, which minimizes restrictions on sidewalks or road traffic. Construction debris, dust, and noise are also reduced. There are no changes in structural engineering due to deep excavations, and the construction time is shortened. As a result, the short liner method is many times more economical than the complete replacement of pipes using the open cut method. In addition, both horizontal and vertical pipe and sewer lines can be rehabilitated using liners.
