If a clogged or broken sewer line is not remedied with a traditional drain cleaning, your plumber may recommend sewer excavation to remove the damaged section and install a new pipe. While this repair method is often the most effective, it can be more invasive to your home and property than less intrusive options such as trenchless pipe-bursting. In this article, we will explain what is involved in sewer excavation and discuss the advantages of more advanced sewer line replacement methods that avoid the need for digging up your property.URL : https://valleyviewexcavatingllc.com/excavation/sewer/
What are the steps involved in the construction of a sewer line?
When a plumber recommends sewer excavation, they will first locate your sewer line, ideally with a video camera inspection that will give them a clear view of the entire length of your underground plumbing lines. Then they will call your local utility locator to have all buried service lines marked before the excavation work begins. This step is extremely important; it ensures that the team will not accidentally hit any lines, which can result in major repairs and service interruptions to your home.
Once the team is onsite, they will begin digging up your sewer line with heavy excavation equipment like backhoes and excavators. They will dig a trench along the path of your sewer line, minimizing side-digging as much as possible until they have located the line.
To prevent cave-ins, the crew may install various protection systems on the walls of the trench. Some of these include sloping the trench wall, benching the trench wall, and curing-in-place piping. Depending on soil conditions, these protective systems may need to be adjusted regularly to account for shifting earth and changing weather. A competent person should also periodically inspect the trench to determine if there is a situation that could cause a collapse (e.g., water accumulation, equipment failure, or a hazardous atmosphere).
