Types of Trenchless Sewer Line Services
Trenchless methods offer Knoxville homeowners efficient, durable solutions that restore their sewer system with minimal digging. Our specialized processes ensure accurate diagnosis and long-term repair by utilizing these primary techniques:
Pipe Lining (Cured-In-Place Pipe)
We insert a custom-made liner into the damaged existing pipe. The liner then cures, hardening to create a brand-new, structural pipe within the old one. This method fixes cracks and breaks without requiring extensive trenching. The resulting pipe is seamless, preventing future intrusion from tree roots and sealing small leaks caused by wear and tear. This process effectively rehabilitates the entire length of the pipe, replacing it from within. It strengthens the line more than the original structure and restores optimal flow capacity.
Pipe Bursting
The pipe bursting technique pulls a new pipe through the path of the existing damaged line. A bursting head simultaneously breaks apart the old pipe while installing the full-diameter replacement pipe. It requires only two small access points, drastically limiting excavation. When the existing pipe collapses or deteriorates, pipe bursting is the ideal solution. This method completely replaces the old structure by pushing a new, high-density polyethylene (HDPE) pipe through the old line.
Sewer Camera Inspections
Our technicians use specialized, high-resolution cameras to navigate and inspect the entire sewer line. This non-invasive diagnostic step accurately locates and identifies blockages, breaks, and root intrusion, enabling us to choose the most effective repair strategy. The video footage allows us to provide a visual, objective assessment of your sewer line’s condition.
