Traditional sewer line repair or on-site repair involves excavating and even removing a wall to replace the entire pipe. This type of repair is faster, unless the blockage has returned to the main sewer line or affects more than one pipe. This allows you to repair the sewer pipe faster with less damage to the area.

It is possible to repair only the sewer without replacing the entire pipe. Existing sewers can also be covered with a kind of casing to avoid cracks in the pipes. Hydraulic power can be used to break parts of the pipe, and new seamless pipes can be used to replace the broken parts.

This trenchless method uses hydraulics to further break down the old damaged pipe and smoothly replace it with new pipe. In the event of a complete line break or interruption, repair usually requires excavation of the old system and installation of a complete replacement system. For example, if a pipe collapses, leans backward, or has the wrong slope, trenchless repair methods may not work.

Whether trenchless sewer repair is right for you depends largely on the condition of the damaged pipes. The only way to determine if trenchless sewer repairs will solve your particular problem is to have a qualified Philadelphia or Horsham sewer repair contractor come out and inspect the problem.
