When it comes to addressing damaged sewer lines, pipe relining has revolutionized the plumbing industry. This trenchless technology offers a less invasive, more efficient solution compared to traditional methods. But how does the pipe relining process actually work? In this blog, we’ll break down each step of the process so you can understand how this innovative approach restores your pipes and prevents further issues.

 

Step 1: Initial Inspection and Assessment

The first step in the pipe relining process is to assess the condition of your sewer line. This involves:

• CCTV Camera Inspection: A small, high-resolution camera is inserted into the pipe to identify the location and extent of the damage. This inspection helps the plumbing team determine if pipe relining is a suitable solution.
• Cleaning and Preparation: Before relining can begin, the pipe must be thoroughly cleaned to remove blockages, debris, and any buildup. This is typically done using methods like hydro jetting or mechanical cleaning tools.

 

Step 2: Measuring and Preparing the Liner

Once the pipe is clean and inspected, the next step is to prepare the liner:

• Custom Measurements: The damaged section of the pipe is measured to ensure the liner will fit perfectly. Precision is crucial for a seamless repair.
• Impregnation with Epoxy Resin: A flexible liner, often made of felt or fiberglass, is impregnated with a two-part epoxy resin. This resin is the material that will cure to form the new pipe.

 

Step 3: Inserting the Liner

With the liner prepared, it’s time to insert it into the damaged pipe:

• Inversion or Pull-in Method:
  • Inversion Method: The liner is inverted (turned inside out) as it is pushed through the pipe using air or water pressure. This ensures the resin-coated side adheres to the inside of the existing pipe.
  • Pull-in Method: The liner is pulled into place using a cable or winch system.
• Positioning the Liner: The liner is carefully positioned to cover the damaged areas of the pipe.

 

Step 4: Curing the Liner

Once the liner is in place, it needs to harden and form a new pipe within the old one:

• Curing Process:
  • Hot water, steam, or UV light is used to cure (harden) the epoxy resin. The curing method depends on the specific materials and conditions of the repair.
• Timeframe: Curing typically takes a few hours, but the exact time depends on the length of the pipe and the resin used.

 

Step 5: Final Inspection

After the liner has cured, the newly formed pipe is inspected to ensure the repair was successful:

• Post-Repair Camera Inspection: The camera is reinserted into the pipe to check for proper installation and ensure there are no remaining issues.
• Smooth Interior: The relined pipe should have a smooth interior surface that improves flow and resists corrosion and root intrusion.

 

Benefits of Pipe Relining

The pipe relining process not only repairs your damaged sewer lines but also provides numerous long-term benefits, including:

• Durability: The new pipe can last 50 years or more.
• Resistance to Root Intrusion: The seamless, joint-free design prevents roots from penetrating the pipe.
• Improved Flow: The smooth interior reduces friction, enhancing water flow.
• Minimal Disruption: Since it’s a trenchless method, pipe relining avoids extensive digging and property damage.
