Trenched Sewer Line Repair
The most common form of repair for damaged sewer lines is to dig a trench, replace the damaged sewer line, and re-establish the connection that previously existed. The necessity of a trenched connection is something that would be determined after an inspection. Of course, retrenching a sewer line is also the most expensive form of residential sewer repair, which can involve digging up a large area, as well as tearing up the sidewalk or street near the home. In many cases, traffic may have to be rerouted, and the repair can cost in the tens of thousands of dollars. Because of this, many homeowners are less than enthusiastic about repairing damaged sewer lines. Because of this, alternative technologies have been developed that are less invasive and expensive.
Trenchless Sewer Repair: Pipe Bursting
In the past couple of decades, pipe bursting has become increasingly popular as a method to replace pipes with minimal digging. Pipes are extended through a method which destroys the blockage, allowing for a replacement to be attached at the other end. In most cases, the pipes are rerouted, which allows for easier access to sewer mains and can even be done above ground. These methods can use a variety of materials, and they can be used in many residential piping systems. Since a trench isn’t required, less space is taken up, and repairs are often thousands of dollars less. However, due to the nature of attempting to burst what is causing a blockage or leakage underneath, in some scenarios, bursting is not an effective method to repair the line. In such cases, pipe lining is often used as an alternative.
Trenchless Sewer Repair: Pipe Lining
In cases where pipe bursting is not an option, pipe lining is extremely popular. Pipe lining involves using a high density plastic such as PVC, coated with resin to create a connection around the downed pipe, which is then inserted into the pipe mouth. After a few hours, the resin hardens, creating a solid block against any form of leakage. This is usually the cheapest method for trenchless sewer repair. However, its application is limited; in cases where there is damage to a pipe caused by a blockage, a bursting may need to be done first. However, this method has become increasingly popular with homeowners overall.
