Collapsed Sewer Line

Collapsed sewer lines are commonly the end result of several types of untreated sewer line problems. Tree root incursion, offset pipe joints, and aging orangeberg pipe – if left untreated – lead to the loss of structural integrity of the sewer pipe which eventually leads to the soil above collapsing into the line and completely blocking the flow of wastewater. Once a pipe has collapsed, either repair or replacement is typically needed to restore flow.


Underlying Causes Of Collapsed Sewer Pipes

Tree Root Incursion Weakens Pipe Wall

Tree roots seeking out water are attracted to the available moisture in the sewer line and grow into the pipe through joints. As the roots grow they weaken the joint allowing wastewater to escape and erode the soil around the pipe creating a belly that results in collapse.

Offset & Misaligned Pipes

Similar in effect to tree roots, offset or misaligned joints allow wastewater to escape which erodes soil around the pipe eventually leading to collapse.

Aging Orangeberg Pipe

Orangeberg pipe is a compressed tar paper pipe which was manufactured during WWII as metal was diverted towards the war effort. After decades of use, these tar paper pipes degrade from the constant moisture causing the pipe walls to weaken and collapse.

Collapsed Pipe Repair Procedure & Options

Step 1: Get Your Sewer Flowing & Diagnose The Cause

Rooter & Drain Cleaning
Getting your waste water flowing again is the first priority. While rooter service is only a temporary fix aimed at the symptom - not the cause - our technicians will clear the line (if necessary) in order to get waste water flowing and prepare the line for video inspection.

Video Camera Inspection
After the line has been cleared so that it is visible, the next critical step is to visually inspect the length of the sewer line with a video camera inspection. With a visual inspection, technicians can then accurately diagnose the situation and come up with options that fit the issue.

Step 2: Get Multiple Options To Permanently Solve The Issue

Hydrojetting is a more permanent solution than rooter service. Instead of punching a hole through a blockage to get waste water flowing, hydrojet cleaning uses high pressure water jets to scour the inside of the line to remove grease buildup and even tree roots for a longer lasting effect.

Pipe Lining
Pipe lining is a process of creating a new seamless plastic pipe within the old pipe. The process can be applied to completely replace the line or for spot repairs of problem sections - all without the expense and damage of conventional trenching methods. Because the new pipe is seamless high grade epoxy, weak joints are eliminated leading to a permanent solution.

Pipe Bursting
Pipe Bursting - like pipe lining - is another method used to produce a permanent solution for sewer backups. A pipe bursting head is hydraulically pulled underground to simultaneously break apart the old pipe (even cast iron) while pulling into place a new seamless HDPE pipe. Pipe bursting sewer replacements come with a lifetime warranty.
