5 Issues Trenchless Sewer Repair Can Fix
Not all sewer line repairs are invasive. Trenchless sewer repair uses a liner that is pulled through the pipe and cured in place, with no need for digging.
1. Corrosion
Corrosion and rust are sometimes an issue with cast iron sewer lines. The pipe itself is still relatively whole, but small pinprick leaks begin to develop, and these can lead to raw sewage in the yard. Since the pipe doesn't typically have any major obstructions, just leaks, it is a relatively easy process to pull a liner into place and seal up all the corrosion damage. The liner also protects the pipe from moisture, which slows down corrosion.
2. Root Incursion
Tree roots grow into sewer lines via small cracks and pipe joints. Over time, the roots force apart the pipes at the entrance point, causing leaks to develop. Trenchless repair can seal up these gaps, but regular root treatments will be needed to prevent future damages unless the trees are removed. First, the repair team will clean the line to remove existing roots, then they will deploy the pipe liner.
3. Soil Shifts
Shifting soil can move a sewage line slightly, which results in pipe sections that don't line up completely. This causes gaps in the line, leading to a sewage leak in the yard. As long as the pipes are aligned enough to pull the liner through them, trenchless repair is a possibility. The pipe liner will seal over any gaps or cracks that developed due to the shifting soil so that there will be no more leaking from the sewer line.
4. Small Cracks
Smaller cracks develop for a variety of reasons, from minor soil shifts to simple aging. On their own, these cracks aren't a concern, but slow seepage of sewage may become a worry if there are a lot of small cracks. Relining the pipe via a trenchless repair seals the myriad of small cracks. Not only does this prevent leaking, but it also minimizes the chances of the damage worsening over time.
5. Minor Collapse
Sometimes a pipe collapses from soil pressure or tree root constriction. If the pipe is collapsed to the point that sewage can barely pass through, then trenchless repair isn't an option because a liner can't be pulled through. For minor collapses, though, trenchless repair is an option as long as the opening through the collapse is large enough for the liner. When the liner is expanded and cured, it will open up the constricted area for better sewage flow.
