How Does Trenchless Sewer Repair Work? Exploring the Efficient Process

Trenchless sewer repair is an innovative method used to fix damaged sewer lines without having to dig up large trenches in your yard. This process involves two main techniques: pipe lining and pipe bursting.

Pipe lining starts with a thorough inspection of the sewer line using a small camera that is inserted into the pipe. This allows the technician to identify the location and extent of any damage or blockage. Once the assessment is complete, a flexible resin-coated liner is inserted into the damaged pipe. This liner is then inflated, and the resin is cured, creating a new, durable inner pipe within the existing damaged pipe. The new liner seals off any cracks or leaks, restoring the functionality of the sewer line.

Pipe bursting, on the other hand, is used when the existing sewer line is beyond repair. In this technique, a new pipe is pulled through the old damaged pipe, simultaneously fracturing the old pipe outward. As the new pipe is drawn into place, it effectively replaces the damaged pipe. This eliminates the need for extensive digging, as the bursting head equipment does the hard work of breaking up the old pipe.

Both pipe lining and pipe bursting eliminate the need for disruptive and costly excavation, minimizing damage to your property and reducing the time required for repair. Trenchless sewer repair is a modern solution that ensures efficient and reliable restoration of your sewer system while safeguarding the beauty and functionality of your surroundings.
