Trenchless Basics: What Is CIPP Lining?
Cured-in-place pipe (CIPP) lining represents the gold standard in trenchless pipe rehabilitation technology. This innovative method creates a new pipe within your existing damaged pipe without disruptive excavation. For plumbing professionals and property owners alike, CIPP lining offers an efficient, cost-effective solution for pipe restoration that significantly extends infrastructure lifespan.
CIPP Lining Lifespan: What to Expect
When professionally installed, CIPP lining typically lasts 50-60 years in residential applications, potentially extending total pipe life to 100 years.
CIPP technology allows repair companies to rehab sewer and potable water pipelines without excavation and with only minimal downtime for customers. By adding 50 years to the life of underground pipe systems without digging, developed urban and suburban communities can keep running smoothly while the infrastructure is rebuilt.
6 Factors That Affect CIPP Lining Durability
Understanding what impacts CIPP lining performance helps you provide better service and more accurate information to your customers.
1: Root Intrusion Management
Enemy Number One for aging sewer lines is root intrusion. No matter where in the country you work, you’re going to find sewer pipes clogged and broken by root systems. And while CIPP repairs can mitigate future intrusions, it isn’t always a guarantee that the roots won’t cause future damage.
Blocked pipe caused by ingress of tree roots.
Talk with property owners about potential changes to landscaping and vegetation that could cause repeated problems. Root barriers and removal of major vegetation could be necessary in some cases.
The good news? Most CIPP repairs create a strong enough barrier between the pipe and the surrounding soil that new roots won’t cause damage.
2: Seismic Activity and Ground Movement
In places where seismic activity is more common, like southern California, ground shifts can cause major problems with underground utilities. CIPP repairs can fix cracked pipes, but ground movement can rupture these repairs. Even conventional trenching repairs can still be disturbed by earthquakes or ground shifts, so the longevity of repairs depends on the seismic activity of the area to at least some extent.
3: Pipe Usage and Materials
“High-volume use or corrosive materials can decrease the durability of the resin liner in some cases.”
In residential settings, that 50-60 years is nearly a given. But in industrial, commercial, and institutional settings, that time frame will decrease. High-volume use or corrosive materials can decrease the durability of the resin liner in some cases.
Four key factors that can reduce CIPP lifespan:
Corrosive chemicals
Extreme temperatures
Industrial waste products
Throughput volume
For non-residential applications, consider using specialized formulations designed for higher chemical resistance or temperature tolerance.
4: Proper Curing Protocols
Your curing process will either provide another half-century of use or leave your customers searching for another contractor. The difference is quality control.
If you’re not getting your cure right, you’ll start seeing:
Bubbling between liner and host pipe
Liner slippage or displacement
Reduced chemical resistance
Compromised structural integrity
We’ve seen just about every scenario for poorly cured liners, and we’ve helped small businesses overcome them through proper training and support. The most common issues with curing start with these simple factors:
Improper resin ratios and use of activators
Inadequate resin mixing
Curing too fast or too slow due to climate
But when you know your equipment, materials, and processes inside and out, issues like this solve themselves. Once our clients get their teams in sync with best practices, their customers no longer have to worry about improper curing.
T3’s SpeedyLight UV Curing System in Action
If you’re concerned about the curing time, using UV light-curing resin instead of conventional epoxy could be worth the investment. UV curing takes only 90 seconds to complete, making the line operational in only a few hours from start to finish.
Curing Time Comparison
| Curing Method | Typical Completion Time | Benefits |
|---|---|---|
| Ambient Curing | 12-24 Hours | Lower Equipment Costs |
| Hot Water Curing | 3-6 Hours | More Consistent Results |
| Steam Curing | 2-4 Hours | Faster Turnaround |
| UV Light Curing | 90 Seconds* | Extremely Rapid Completion |
*Total installation still requires several hours for preparation and finishing; all ambient, hot water, and steam curing times are climate-dependent.
5: Installation Methods
The best plumbing and pipe repair businesses know this simple truth: standard operating practices are foundational to excellent service. When teams don’t follow protocol, you’ll end up with lower-quality work, less consistent results, and more callbacks.
Top Installation Errors to Avoid:
Improper pipe cleaning before installation
Incorrect resin mixing ratios
Inadequate liner saturation
Insufficient inflation pressure
Premature termination of curing process
Take the time to build quality control protocols and best practices, as well as a troubleshooting guide for new (and even experienced) installers.
6: Environmental Factors
Local environmental conditions (soil composition, groundwater levels, and temperature fluctuations) influence CIPP performance over time. During your assessment phase, document these factors to provide more accurate lifespan estimates.
Knowing your service area’s most common conditions can also help you determine your best standard warranty period for each job type, making it easier to provide peace of mind to your customers.
6 Pro Ways to Maximize Your CIPP Lining’s Lifespan
Follow these industry-proven best practices to ensure your CIPP installations consistently provide their maximum lifespan.
1: Comprehensive CCTV Inspection
Every successful CIPP project begins and ends with a thorough visual inspection. Modern CCTV technology allows you to:
Identify the precise location and extent of damage
Document pre-existing conditions
Determine best repair approaches
Verify successful installation
Provide quality assurance documentation
Better installations start with detailed inspection records. Include date-stamped videos for each project, as well as both initial assessments and final condition.
2: Proper Pipe Preparation
A clean pipe makes for a great installation. A dirty pipe makes for a long reinstall. Start your CIPP installation right with cleaning processes that get your host pipe ready.
Hydro Jetting
Clean rust, dirt, and debris from pipes before relining with T3 chain knockers.
High-pressure water technology removes:
Scale buildup
Grease accumulation
Root intrusions
Sediment deposits
Chain Knockers
These specialized tools excel at removing:
Tuberculation
Hard mineral deposits
Stubborn debris
Chain knockers utilize a steel cable with attached metal chains that spin at high speeds, dislodging even the most stubborn buildup.
Best Practice: Use a cleaning process that matches with pipe condition. For more brittle or rusted pipes, chain knockers may be too aggressive, whereas hydrojetting may not completely clean pipes with greater buildup.
3: High-Quality Materials
The quality of your liner materials and resins directly determines installation longevity. Look for:
Resin formulations appropriate for application conditions
Liner materials suited to pipe diameter and configuration
Manufacturer warranty coverage
Independent/third-party testing and benchmarking
While premium materials increase upfront costs, they reduce callback rates and warranty claims while enhancing your reputation for quality.
4: Technical Training and Support
Even the finest materials won’t make up for poor installation techniques. Invest in comprehensive training for your technicians, including:
Equipment-specific operation protocols
Material handling best practices
Curing process management
Quality control procedures
Troubleshooting techniques

Your CIPP liner will only be durable if it’s been prepared properly. Make sure your teams check off the following core protocols:
Accurate resin-to-hardener ratios
Complete resin impregnation
Proper temperature control
Appropriate activator use
Careful handling to prevent contamination
Pro Tip: Even minor deviations in resin mixing can dramatically affect cure time, adhesion quality, and long-term performance. Value precision over speed.
High-Quality Tools and Equipment
While purchasing used equipment could save some money upfront, investing in top-tier equipment pays dividends through:
More consistent installations
Reduced labor requirements
