Sewer line repair and replacement is one of the most difficult and resource-intensive plumbing projects. This is mainly because most of the sewer system is buried below the ground. You need specialized plumbing equipment to access these underground sewer lines for repairs and replacements. Actually you first need to inspect these underground sewer lines to determine where the damage is and how to fix it. If you have clogged or leaking sewer lines in your house, you should first request Cincinnati sewer inspection services. Hire a competent plumber who can conduct underground sewer camera inspections to determine the exact nature and position of the problem in your sewer lines. After discovering the sewer line problem, you can now proceed to choose the best method for repairing or replacing your underground sewer lines. Nowadays most plumbers recommend various trenchless sewer repair methods. Trenchless sewer repair does not involve ground excavation to access the damaged sewer lines. Today we are going to compare the two main types of trenchless technologies that you can use to repair your underground sewer lines.

Cured-In-Place Pipe (CIPP) Lining

Cured-in-place pipe (CIPP) lining or slip lining is a trenchless method of repairing pipes in their original place. It’s implemented as a seamless, jointless pipe rehabilitation process. A resin-saturated polyester or fiberglass tubing is inserted and pulled through the damaged sewer line. The resin is then cured using hot air and/or water pressure to form a permanently sealed jointless and noncorrosive pipe-within-a-pipe. Let us now look at the advantages and disadvantages of the CIPP method.

Advantages Of CIPP

The CIPP lining method requires minimal excavation. In fact you only need an insertion and an exit or lateral point. This means that armed with all the necessary equipment, the CIPP method is easier, faster, and cheaper to implement. Another advantage of the CIPP method is that it reduces root and water infiltration. The CIPPP method produces a jointless seamless sewer pipe that has no joints for root infiltration. The CIPP method is suitable for unpaved areas because it does not involve any excavation.

Disadvantages Of CIPP

One of the main disadvantages of CIPP is that it can release a hazardous chemical called styrene to storm water drainage. Another major disadvantage of CIPP is that it takes longer to implement than pipe bursting. CIPP reduces the interior diameter of the new pipe. The new pipe is installed inside the damaged one thereby reducing the interior diameter and this can undermine the longevity of your sewer lines.

Pipe Bursting

Pipe bursting is a trenchless sewer line technology used for replacing damaged underground sewer lines. A new pipe is inserted inside the old pipe and pulled through thereby fracturing and destroying the existing pipe. The new pipe can be pulled pneumatically, statically, or through hydraulic expansion. The following are some of the pros and cons of pipe bursting.

Advantages Of Pipe Bursting

Like CIPP, pipe bursting involves minimal excavation. It’s easier, cheaper, and faster to implement in unpaved areas. The inserted pipe is jointless and seamless which curbs root and water infiltration. Unlike CIPP, pipe bursting can actually increase the diameter of the underground sewer line. Pipe bursting does not use any hazardous chemicals and the inserted pipe can last for a very long time.

Disadvantages Of Pipe Bursting

Pipe bursting requires sophisticated plumbing equipment to implement and can hence be more expensive than the traditional open cut sewer excavation method. This is especially so in unpaved areas.
