Causes of Sewer Line Breaks, Leaks and Cracks
Now that we’ve learnt what is trenchless sewer repair, it’s time to understand what causes sewer lines to get damaged:
Here are the factors that often necessitate trenchless sewer line repair:
Aging Infrastructure:
Many sewer systems across the country are aging, with pipes dating back several decades.
Over time, these pipes may deteriorate due to factors like corrosion, wear and tear, and material degradation. Trenchless sewer repair becomes essential to address the inevitable breakdown of these aging sewer lines.
Ground Shifting and Settlement:
Natural phenomena such as ground shifting, settling, or upheaval can exert immense pressure on underground sewer pipes. This can lead to misalignment, cracks, or even complete pipe collapse, requiring prompt trenchless sewer line repair to restore proper functionality.
Tree Root Intrusion:
Tree roots are notorious for seeking out sources of moisture, including sewer pipes. As roots infiltrate the pipes through small cracks or joints, they can cause blockages, leaks, and structural damage. Trenchless sewer repair techniques are effective in removing tree roots and restoring the integrity of the sewer line.
Poor Installation or Construction:
In some cases, sewer pipes may fail prematurely due to improper installation or the use of substandard materials during construction. Trenchless sewer line repair offers a viable solution to rectify these issues without the need for extensive excavation or disruption.
Environmental Factors:
Environmental factors such as seismic activity, soil erosion, or chemical exposure can compromise the structural integrity of sewer pipes. These external forces can contribute to cracks, fractures, or corrosion, necessitating timely trenchless sewer repair to prevent further damage.
High-Pressure and Heavy-Duty Usage:
Sewer lines in commercial or industrial areas often experience high volumes of wastewater flow and greater pressure. Over time, this relentless wear and tear can weaken the pipes, leading to leaks, collapses, or other failures that warrant trenchless sewer line repair.
Infiltration and Inflow:
Infiltration refers to the entry of groundwater into sewer pipes through cracks or defects, while inflow refers to the introduction of surface water during heavy rainfall or flooding events.
Both infiltration and inflow can overwhelm sewer systems, leading to backups, overflows, and structural damage that necessitate trenchless sewer repair interventions.
Signs That Indicate You Need a Trenchless Sewer Repair
Recognizing the signs of sewer line problems early on is crucial for homeowners and property managers to prevent extensive damage and costly repairs. Here are several indicators that may suggest the need for trenchless sewer repair:
Persistent Drain Clogs:
One of the most common signs of a sewer line issue is recurring or persistent drain clogs throughout the property. If multiple drains, such as sinks, toilets, or showers, are slow to drain or frequently clog despite attempts to clear them, it could indicate a blockage or damage within the sewer line.
Foul Odors:
Unpleasant odors emanating from drains, the yard, or near the foundation of the property may signal a sewer line problem. Sewage smells often indicate the presence of a leak, crack, or other damage in the sewer line, allowing sewage gasses to escape into the surrounding environment.
Slow Draining Fixtures:
Slow draining sinks, showers, or toilets are not only inconvenient but also indicative of potential sewer line issues. If multiple fixtures in the property exhibit sluggish drainage despite efforts to unclog them, it may be a sign of obstruction or damage within the sewer line.
Sewage Backups:
Sewage backups are a serious and alarming indication of a sewer line problem. If sewage or wastewater backs up into drains, toilets, or other fixtures within the property, it suggests a blockage, partial collapse, or severe damage in the sewer line that requires immediate attention.
Standing Water or Soggy Areas:
The presence of standing water or soggy areas in the yard, particularly near the location of sewer lines, may indicate a leak or break in the sewer pipe underground. These wet patches may develop due to sewage seepage or water escaping from a damaged sewer line.
Foundation Cracks or Settlement:
Structural issues such as cracks in the foundation or settlement of the property may be linked to sewer line problems. When sewer pipes leak or break underground, the excess moisture can destabilize the soil, leading to foundation issues over time.
Rodent or Insect Infestations:
Infestations of rodents, insects, or other pests within the property may be attracted to the presence of sewage leaks or standing water caused by a damaged sewer line. If unexplained pest activity is observed indoors or near sewer access points, it could indicate a hidden sewer line issue.
High Water Bills:
A sudden or unexplained increase in water bills without a corresponding increase in water usage may point to a hidden leak or break in the sewer line. Water escaping from a damaged sewer pipe underground can contribute to inflated water bills over time.
By remaining vigilant for these telltale signs of sewer line problems, property owners can promptly address issues before they escalate into larger and more costly repairs.

The Two Major Methods of Trenchless Sewer Repair: Pipe Lining and Pipe Bursting
Trenchless sewer repair encompasses a variety of innovative techniques designed to rehabilitate or replace underground sewer pipes without the need for extensive excavation.
Among these methods, pipe lining and pipe bursting stand out as the two primary approaches, each offering unique advantages depending on the specific needs and conditions of the sewer line. Let’s explore these two major methods in greater detail:
1. Pipe Lining
Pipe lining, also known as cured-in-place pipe (CIPP) lining, is a trenchless sewer repair method that involves the installation of a durable, seamless liner within the existing damaged pipe. Here’s how the process works:
Inspection and Preparation: The first step in pipe lining involves a thorough inspection of the sewer line using advanced camera technology to assess the extent and nature of the damage. Once the assessment is complete, the sewer line is cleaned and prepared for the lining process.
Liner Installation: A flexible liner saturated with epoxy resin is inserted into the damaged pipe using air or water pressure. The liner is positioned precisely within the pipe using a calibration tube or inversion process, ensuring a snug fit against the pipe walls.
Curing Process: Once in place, the liner is inflated and exposed to heat or ultraviolet light, causing the resin to cure and harden. This creates a durable, seamless “pipe within a pipe” that effectively seals cracks, leaks, and other defects in the original pipe.
Quality Assurance: After the curing process is complete, the newly lined pipe undergoes a final inspection to ensure proper installation and adherence to quality standards. Once approved, the sewer line is ready for immediate use, with minimal disruption to the surrounding environment.
Pipe lining is particularly well-suited for repairing small to moderate defects in sewer pipes, including cracks, corrosion, and root intrusion. It offers several advantages, including cost-effectiveness, minimal excavation, and faster completion times compared to traditional pipe replacement methods.
2. Pipe Bursting
Pipe bursting is another trenchless sewer repair method used to replace existing sewer pipes with new, high-density polyethylene (HDPE) pipes. This method involves breaking apart the old pipe while simultaneously pulling in the new pipe, creating a seamless and durable replacement. Here’s how pipe bursting works:
Access and Preparation: Access pits are excavated at either end of the sewer line to be replaced. A hydraulic pulling machine and bursting head are inserted into the starting pit, while a winch and pulling cable are fed through the receiving pit.
Bursting Process: The bursting head, equipped with cutting blades, is guided through the old sewer pipe, fracturing it into fragments that are pushed into the surrounding soil. At the same time, the new HDPE pipe is attached to the pulling cable and drawn into place behind the bursting head.
Alignment and Connection: As the bursting head advances through the old pipe, it ensures proper alignment and clearance for the new pipe. Once the bursting process is complete, the new pipe is securely connected to the existing sewer system, typically through manhole access points.
Finalization and Restoration: After the new pipe is in place, any remaining access pits are backfilled, and the site is restored to its original condition. The result is a seamless and durable replacement sewer line that meets or exceeds industry standards.
Pipe bursting is well-suited for replacing larger sections of sewer pipe or pipes that are severely damaged or collapsed. It offers several advantages, including minimal disruption to surface infrastructure, reduced risk of environmental contamination, and increased flow capacity compared to the original pipe.
If we compare both, pipe lining and pipe bursting are effective trenchless sewer repair methods that offer distinct advantages depending on the specific circumstances of the sewer line.
