Solutions for Collapsed Sewer Lines 

collapsed sewer lines

Collapsed sewer lines are a dilemma for any plumbing system, as they are responsible for adequately disposing of wastewater from homes and buildings. However, these lines can become damaged or collapse over time, leading to many problems for homeowners and the community. A collapsed sewer line can cause blockages, backups, and even sewage spills, which are hazardous to human health and the environment. 

Read on as we explore some tested and proven pipe solutions for collapsed sewer lines.

What Causes Collapsed Sewer Lines?

A sewer can collapse for several reasons, including age, wear, and erosion. Over time, the sewer line can become weak and brittle, leading to cracks and breaks. Tree roots can also invade the pipes, causing them to crack or collapse. Soil erosion can also cause the ground to shift, putting pressure on the pipes and leading to collapse.

When these issues happen, indicators like backed-up sinks, foul odors, slow drainage, and uneven yard growth usually result, causing major inconveniences in your home or building. 

What Are the Best Solutions for Collapsed Sewer Lines?

A collapsed sewer line can lead to sewage backups, water damage, and structural problems if left unattended. It can also pose a health hazard by exposing you and your family to harmful bacteria and gases.

Fortunately, trenchless technology provides a non-invasive solution for repairing or replacing a damaged sewer line. It allows technicians to fix the problem without excavation, which means less disruption to your property and lower repair costs.

Here are some common trenchless pipe repair solutions:

Cured-in-Place Pipe Lining

One of the most popular trenchless methods for repairing collapsed sewer lines is cured-in-place pipe lining. CIPP involves inserting a flexible liner into the damaged sewer line, inflating it, and hardening it in place with hot water or steam. The liner creates a new and durable pipe within the existing one, eliminating the need for excavation. This method is particularly useful when the damaged pipe is inaccessible or in a tight space, such as directly beneath delicate infrastructure.

Pipe Bursting

Pipe bursting involves breaking the existing damaged pipe while simultaneously pulling a new pipe through the old one. The new pipe bursts the old one, pushing the debris into the surrounding soil. Pipe bursting is particularly useful when the existing pipe is too damaged for the lining.


Slip-lining involves inserting a smaller, flexible pipe into the damaged sewer line, which acts as a new liner. The liner consists of durable materials such as high-density polyethylene, which experts insert into the old pipe and expand to fill the entire pipe. The new pipe creates a smooth inner surface that helps prevent future blockages and leaks. 

If you suspect that you have a collapsed sewer line, then you need prompt assistance. It is essential to contact a professional CIPP technician to inspect the damage and determine the correct fix.
