Why You'll Love Perma Liner Lining
-
No excavation required.
Your landscaping, concrete driveways, patios, and walkways stay completely intact. Zero excavation repairs are advantageous in urban environments like Nashville, where properties are close together and yards are tight.
-
Saves you serious money.
It costs 30-50% less than traditional dig-and-replace methods when you factor in the restoration of surfaces, landscaping, and concrete that excavation destroys. This is a genuinely cost-efficient alternative to traditional pipe repair methods.
-
Completed fast.
Most residential jobs wrap up in 1 to 2 days for larger jobs, compared to weeks of disruption with traditional excavation. Some cured-in-place-pipe systems can be installed in as little as 20 minutes for certain sections.
-
50-year design life.
The technology complies with ASTM standards and is designed for a 50+ year lifespan. Perma-Liner offers a 50-year design life warranty on products, so you are covered for the long haul.
-
Stops problems at the source.
The epoxy-coated liner is resistant to corrosion and root penetration, so those recurring backups and slow drains become a thing of the past.
What Makes Our Perma Lining Different
Most plumbers in Middle Tennessee still rely on the old way of doing things. They dig a trench, rip out the old pipe, and replace it. That means costly excavation, weeks of mess, and a yard that looks like a construction zone when they leave.
Coolray's perma lining approach is built differently:
- Certified installation expertise. Our team uses premium Perma-Liner materials with a proven track record across north america. Perma-Liner is the first CIPP company approved by NSF International, which means the materials meet the highest safety and performance standards in the contracting industry.
- Advanced equipment and techniques. We use high-definition camera inspection systems, hydro-jetting equipment for pipe preparation, and heat assist equipment for proper curing. Whether the liner is air inverted, steam cured, or ambient cured, we match the right pipe repairing techniques to your specific situation.
- 10-year parts and labor warranty on all installations, backed by our Coolray guarantee plus the manufacturer warranty. That kind of coverage is hard to find.
- Same-day service availability for emergency situations, because a failing underground sewer does not wait for a convenient time.
How Cured in Place Perma Lining Works
- Camera Inspection We start every broken pipe repair project by sending a high-definition camera through your sewer lines. Inspection involves using high-definition cameras to evaluate the condition of your pipes, locate cracks, root intrusion, corrosion, and any other damage. This lets us plan the installation precisely and confirm that perma lining is the right fit for your situation. Trenchless repairs can be completed with only one access point, so we often just need a single point through one of your clean outs or even open end pipes to get started.
- Cleaning and Preparation Before any liner goes in, the host pipe needs to be spotless. Cleaning removes debris and tree roots from damaged pipes before lining. We use hydro-jetting to scour the inside of your existing pipes, removing scale, mineral buildup, and root masses. This step is critical because the new pipe liner needs a clean surface to bond properly.
- Liner Installation and Curing Here is where the magic happens. A flexible liner soaked in epoxy resin is inserted into the damaged pipe through the access point. Depending on the situation, the liner can be installed using perma lateral air inversion or a pull in place method, with place lining options that include place pipe cipp techniques for the right application. For larger or municipal jobs, installation may also be completed from a manhole through existing manholes with a manhole inversion rehabilitation system. These newly developed trenchless pipe repair systems use user-friendly equipment and workflow for trained crews, and different pipe liners can also be paired with next generation uv technology when the job calls for it. The curing process can use hot water, steam, or ambient light. Once cured, Perma-Liner creates a durable seamless pipe within the old pipe. The result is a smooth, corrosion-resistant new pipe inside your existing one, and it is installed safely with minimal disruption to your daily routine.

Who It's Perfect For
Ideal for:
- Homeowners with recurring sewer backups or slow drains. If you keep calling a plumber for the same pipeline problems, lining solves the root cause instead of just treating the symptoms before a failing pipeline gets worse.
- Properties dealing with root intrusion. Nashville's sewer systems often consist of clay pipes prone to root intrusion. Tennessee's mature trees are beautiful, but their roots wreak havoc on older clay and cast iron pipes. Perma lining seals every joint and crack so roots cannot get back in, helping prevent leaks and even breakage.
- Homes where excavation would cause expensive damage. If your sewer lines run under a concrete slab, paved driveway, or carefully maintained landscaping, trenchless technology preserves landscaping and historical foundation integrity without the disruption of rebuilding infrastructure versus repairing the line in place.
- Older Middle Tennessee homes with corroded cast iron or crumbling clay pipes. These are the most common candidates we see, and perma lining is perfectly suited for this kind of rehabilitation.
- Properties in tight urban spaces. Simple residential applications in downtown Nashville neighborhoods or dense subdivisions benefit from the minimal footprint of trenchless sewer repair, including vertical pipe repair solutions for high rises and similar properties.
If you want your pipes rehabilitated relined without turning your property into a dig site, this lining system fits your needs.

Frequently Asked Questions
Absolutely. Once the cured in place pipe liner hardens, it becomes a fully structural pipe inside your old one. Repairs can improve flow capacity due to a smooth epoxy surface that actually outperforms the rough interior of aging cast iron or clay. With a 50-year design life and resistance to corrosion and root penetration, you are getting durability that matches or exceeds traditional replacement in most situations.
Most residential perma lining jobs take 1 to 2 days from start to finish. That includes the camera inspection, hydro-jet cleaning, liner installation, and curing. The actual curing stage can happen remarkably fast. Trenchless pipe repair eliminates the need for excavation, which is what saves you all that time compared to traditional methods.
You get our 10-year Coolray guarantee covering both parts and labor on every installation. On top of that, the Perma-Liner manufacturer warranty backs the product with a 50-year design life. We stand behind our work completely.
The liner does add a thin layer inside the pipe, but for standard 4-inch and 6-inch residential pipes, the reduction is minimal. In practice, the smoother epoxy interior actually improves water flow compared to your old, rough, corroded pipe. Most homeowners notice better drainage after installation, not worse.
If your pipe has completely collapsed, has large missing sections, or severe misalignment, traditional replacement may be necessary. That is exactly why we start every job with a thorough camera inspection. We will always be upfront with you about the best approach for your specific situation.
