How CIPP Pipe Lining Works: Step-by-Step Process
A detailed look at the CIPP pipe lining process — from the initial camera inspection through final verification — and why Prodigy Sewer & Drain carries certifications in five different lining systems to match the right solution to every pipe in Franklin and Nashville, TN.
What Is CIPP Pipe Lining?
CIPP stands for cured-in-place pipe. It is a trenchless sewer repair method that installs a new pipe inside your existing one — without digging up your yard, driveway, or foundation. A resin-saturated felt liner is inserted into the damaged pipe and cured (hardened) in place, forming a smooth, jointless pipe-within-a-pipe. The result is a structurally independent new pipe with a 50-year design life.
Prodigy Sewer & Drain is certified in five CIPP lining systems — MaxLiner, Perma-Liner, Hammerhead UV, PRT, and Repiper — so we match the right liner, resin, and curing method to your specific pipe condition rather than forcing a one-size-fits-all approach.
The CIPP Pipe Lining Process: 8 Steps
Every CIPP lining job follows the same disciplined sequence. Here is exactly what happens when Prodigy lines your sewer pipe.
Step 1: Sewer Camera Inspection
We begin with a CCTV camera inspection to map the pipe's condition — cracks, root intrusion, joint offsets, corrosion, and any bellies or deformations. The footage tells us whether the pipe is a candidate for lining or needs pipe bursting or excavation instead. We score the pipe to NASSCO/PACP standards and share the recorded footage with you.
Step 2: Cleaning & Preparation (Hydro Jetting)
Before a liner goes in, the pipe must be completely clean. We use hydro jetting at up to 4,000 PSI to scour away roots, grease, scale, and debris. For cast iron pipes with heavy buildup, we add mechanical descaling. A clean pipe wall is critical — the resin must bond directly to the host pipe surface for a permanent, watertight seal.
Step 3: Liner Measurement & Cutting
We measure the exact length and diameter of the section being repaired and cut the felt liner to fit. Each liner is sized for the specific pipe — there is no trimming or guessing on site. Proper measurement ensures full coverage of the damaged area with no gaps and no excess material.
Step 4: Resin Saturation (Wet-Out)
The cut liner is saturated with a two-part epoxy or vinyl ester resin in a controlled wet-out process. The resin type is matched to the pipe material, soil chemistry, and expected structural loads. This step is done precisely — too little resin leaves weak spots, too much wastes material and extends cure time. Prodigy follows manufacturer-specified resin ratios on every job.
Step 5: Liner Insertion & Inversion
The resin-saturated liner is inserted through an existing access point — usually a cleanout or small access pit — and inverted (turned inside out) into position using calibrated air or water pressure. Inversion presses the resin-coated side against the pipe wall, filling cracks and bridging joint offsets. No excavation is needed for this step.
Step 6: Curing (Ambient, UV, or Steam)
Once in position, the liner is cured (hardened) into a rigid new pipe wall. Prodigy uses three curing methods depending on the system and job conditions: ambient/hot-water cure (MaxLiner, Perma-Liner), steam cure, and UV light cure (Hammerhead UV). UV curing is the fastest, allowing precise control and shorter job times. The curing process transforms the flexible liner into a hard, corrosion-resistant, structural pipe-within-a-pipe.
Step 7: Post-Cure Camera Inspection
After curing, we run a second camera inspection to verify the liner is fully cured, properly adhered to the host pipe, and free of wrinkles or delamination. This footage goes into your warranty file — it is your documented proof that the work was completed correctly.
Step 8: Reinstatement Cutting
If lateral connections (branch lines entering the main sewer) were covered during lining, a robotic reinstatement cutter reopens those connections from inside the lined pipe. A final camera pass confirms every lateral is flowing and the newly lined pipe is fully ready for service.
Five Lining Systems, One Goal
Most lining companies are certified in one system. Prodigy carries certifications in five, which means we choose the right tool for the job — not the only tool we own.
- MaxLiner — ambient and hot-water cured liners for standard residential and commercial sewer lines.
- Perma-Liner — industry-leading CIPP system with a full range of diameter and resin options for gravity and pressure pipe applications.
- Hammerhead UV — UV-cured lining for faster cure times and precision control, ideal for time-sensitive commercial projects.
- PRT (Pipe Restoration Technologies) — structural lining and sectional repair products for targeted, localized fixes.
- Repiper — compact lining solution for smaller-diameter lines and tight-access residential applications.
Why Homeowners Choose CIPP Pipe Lining
- No digging — the liner is installed through existing access points, so your yard, driveway, and landscaping stay intact.
- 50-year design life — the cured liner is a structural, corrosion-resistant pipe that outlasts most original sewer materials.
- 10-year workmanship warranty — Prodigy backs every lining job with a written warranty on our installation work.
- Same-day completion — most residential CIPP lining jobs are completed in a single day, with sewer flow restored before we leave.
- Jointless, root-proof pipe — the seamless liner eliminates the joints where roots enter, solving root intrusion permanently.
- Improved flow — the smooth liner surface reduces friction, often improving flow compared to the original rough or corroded pipe interior.
CIPP Lining vs. Pipe Bursting vs. Excavation
CIPP lining is not the answer for every damaged pipe. Here is when each repair method is the right call.
| Method | Best When | Not Ideal When |
|---|---|---|
| CIPP pipe lining | Pipe holds its shape but has cracks, root intrusion, corrosion, or leaking joints. Ideal under landscaping, driveways, and foundations where digging is costly or destructive. | Pipe is collapsed, severely deformed, has lost more than 40% of its cross-section, or needs upsizing. |
| Pipe bursting | Pipe is collapsed, severely bellied, or needs to be upsized. Works for Orangeburg, clay, and failed cast iron. | Pipe runs under a structure that cannot tolerate ground displacement, or has multiple sharp bends. |
| Excavation | Pipe is under a slab with no alternative access, has multiple sharp bends, or local code requires open-cut replacement. | Accessible yard or driveway where a trenchless method is faster, more affordable, and less destructive. |
Not sure which method your pipe needs? A sewer camera inspection answers that question. We scope the line first and recommend the method that fits — we never push lining on a pipe that needs bursting, or bursting on a pipe that should be lined.
CIPP Pipe Lining Process — Frequently Asked Questions
How long does CIPP pipe lining last?
A properly installed CIPP liner has a 50-year design life. Prodigy backs every lining job with a 10-year workmanship warranty, and the manufacturer warranties the liner materials separately.
How long does the CIPP lining process take?
Most residential CIPP lining jobs are completed in one day — typically 4 to 8 hours depending on pipe length, access conditions, and curing method. UV curing (Hammerhead UV system) is the fastest option.
Can any sewer pipe be lined with CIPP?
The pipe must still hold its round shape. CIPP works on clay, cast iron, PVC, concrete, and Orangeburg pipes that have cracks, root intrusion, or corrosion but are not collapsed. Collapsed or severely deformed pipes need pipe bursting or excavation instead.
Does CIPP lining reduce my pipe's diameter?
The liner reduces the internal diameter by a few millimeters, but the smooth, jointless surface creates less friction than the original rough or corroded pipe wall — so actual flow capacity typically improves after lining.
Will CIPP lining stop tree roots permanently?
Yes. The seamless liner eliminates the joints where roots enter the pipe. Without a gap to exploit, roots cannot re-enter. CIPP solves the root intrusion problem permanently rather than just clearing roots temporarily with a cable or hydro jetter.
What CIPP certifications does Prodigy hold?
Prodigy is certified in five CIPP systems: MaxLiner, Perma-Liner, Hammerhead UV, PRT, and Repiper. Multiple certifications let us match the right liner, resin, and curing method to your specific pipe material and condition.
